•
The Microchip Technology, Inc. MCP651/2/5 family of
operational amplifiers features low offset. At power up,
these op amps are self-calibrated using mCal. Some
package options also provide a calibration/chip select
pin (CAL/CS) that supports a low power mode of operation, with offset calibration at the time normal operation is re-started. These amplifiers are optimized for
high speed, low noise and distortion, single-supply
operation with rail-to-rail output and an input that
includes the negative rail.
Gain Bandwidth Product: 50 MHz (typical)
Short Circuit Current: 100 mA (typical)
Noise: 7.5 nV/√Hz (typical, at 1 MHz)
Calibrated Input Offset: ±200 µV (maximum)
Rail-to-Rail Output
Slew Rate: 30 V/µs (typical)
Supply Current: 6.0 mA (typical)
Power Supply: 2.5V to 5.5V
Extended Temperature Range: -40°C to +125°C
This family is offered in single with CAL/CS pin
(MCP651), dual (MCP652) and dual with CAL/CS pins
(MCP655). All devices are fully specified from -40°C to
+125°C.

CAL/CS Dynamic Specifications
Note 1:

3:
The MCP652 has its CAL/CS input internally pulled down to VSS (0V).
This time ensures that the internal logic recognizes the edge. However, for the rising edge case, if CAL/CS is raised
before the calibration is complete, the calibration will be aborted and the part will return to low power mode.
For the MCP655 dual, there is an additional constraint. CALA/CSA and CALB/CSB can be toggled simultaneously
(within a time much smaller than tCSU) to make both op amps perform the same function simultaneously. If they are toggled independently, then CALA/CSA (CALB/CSB) cannot be allowed to toggle while op amp B (op amp A) is in
calibration mode; allow more than the maximum tCON time (4 ms) before the other side is toggled.

Test Circuits
The circuit used for most DC and AC tests is shown in
Figure 1-2. This circuit can independently set VCM and
VOUT; see Equation 1-1. Note that VCM is not the
circuit’s common mode voltage ((VP + VM)/2), and that
VOST includes VOS plus the effects (on the input offset
error, VOST) of temperature, CMRR, PSRR and AOL.

The analog output pins (VOUT) are low-impedance
voltage sources.
3.2
Analog Inputs
The non-inverting and inverting inputs (VIN+, VIN–, …)
are high-impedance CMOS inputs with low bias
currents.
3.3
Power Supply Pins
The positive power supply (VDD) is 2.5V to 5.5V higher
than the negative power supply (VSS). For normal
operation, the other pins are between VSS and VDD.
Typically, these parts are used in a single (positive)
supply configuration. In this case, VSS is connected to
ground and VDD is connected to the supply. VDD will
need bypass capacitors.
3.4
Calibration Common Mode
Voltage Input
A low impedance voltage placed at this input (VCAL)
analog input will set the op amps’ common mode input
voltage during calibration. If this pin is left open, the
common mode input voltage during calibration is
approximately VDD/3. The internal resistor divider is
disconnected from the supplies whenever the part is
not in calibration.
© 2009 Microchip Technology Inc.
3.5
Calibrate/Chip Select Digital Input
This input (CAL/CS, …) is a CMOS, Schmitt-triggered
input that affects the calibration and low power modes
of operation. When this pin goes high, the part is placed
into a low power mode and the output is high-Z. When
this pin goes low, a calibration sequence is started
(which corrects VOS). At the end of the calibration
sequence, the output becomes low impedance and the
part resumes normal operation.
An internal POR triggers a calibration event when the
part is powered on, or when the supply voltage drops
too low. Thus, the MCP652 parts are calibrated, even
though they do not have a CAL/CS pin.
3.6
Exposed Thermal Pad (EP)
There is an internal connection between the Exposed
Thermal Pad (EP) and the VSS pin; they must be connected to the same potential on the Printed Circuit
Board (PCB).
This pad can be connected to a PCB ground plane to
provide a larger heat sink. This improves the package
thermal resistance (θJA).

MCP651/2/5
4.0
APPLICATIONS
The MCP651/2/5 family of self-zeroed op amps is manufactured using Microchip’s state of the art CMOS
process. It is designed for low cost, low power and high
precision applications. Its low supply voltage, low
quiescent current and wide bandwidth makes the
MCP651/2/5 ideal for battery-powered applications.
4.1
Calibration and Chip Select
These op amps include circuitry for dynamic calibration
of the offset voltage (VOS).
4.1.1
mCal CALIBRATION CIRCUITRY
The internal mCal circuitry, when activated, starts a
delay timer (to wait for the op amp to settle to its new
bias point), then calibrates the input offset voltage
(VOS). The mCal circuitry is triggered at power-up (and
after some power brown out events) by the internal
POR, and by the memory’s Parity Detector. The power
up time, when the mCal circuitry triggers the calibration
sequence, is 200 ms (typical).
4.1.2
CAL/CS PIN
The CAL/CS pin gives the user a means to externally
demand a low power mode of operation, then to
calibrate VOS. Using the CAL/CS pin makes it possible
to correct VOS as it drifts over time (1/f noise and aging;
see Figure 2-35) and across temperature.
The CAL/CS pin performs two functions: it places the
op amp(s) in a low power mode when it is held high,
and starts a calibration event (correction of VOS) after a
rising edge.
4.1.3
This part includes an internal Power On Reset (POR)
to protect the internal calibration memory cells. The
POR monitors the power supply voltage (VDD). When
the POR detects a low VDD event, it places the part into
the low power mode of operation. When the POR
detects a normal VDD event, it starts a delay counter,
then triggers an calibration event. The additional delay
gives a total POR turn on time of 200 ms (typical); this
is also the power up time (since the POR is triggered at
power up).
4.1.4
Once the calibration event is completed, the amplifier is
reconnected to the external circuitry. The turn on time,
when calibration is started with the CAL/CS pin, is 3 ms
(typical).
There is an internal 5 MΩ pull-down resistor tied to the
CAL/CS pin. If the CAL/CS pin is left floating, the amplifier operates normally.
© 2009 Microchip Technology Inc.
PARITY DETECTOR
A parity error detector monitors the memory contents
for any corruption. In the rare event that a parity error is
detected (e.g., corruption from an alpha particle), a
POR event is automatically triggered. This will cause
the input offset voltage to be re-corrected, and the op
amp will not return to normal operation for a period of
time (the POR turn on time, tPON).
4.1.5
CALIBRATION INPUT PIN
A VCAL pin is available in some options (e.g., the single
MCP651) for those applications that need the calibration to occur at an internally driven common mode
voltage other than VDD/3.
Figure 4-1 shows the reference circuit that internally
sets the op amp’s common mode reference voltage
(VCM_INT) during calibration (the resistors are disconnected from the supplies at other times). The 5 kΩ
resistor provides over-current protection for the buffer.
To op amp during
calibration
VDD
While in the low power mode, the quiescent current is
quite small (ISS = -3 µA, typical). The output is also is in
a High-Z state.
During the calibration event, the quiescent current is
near, but smaller than, the specified quiescent current
(6 mA, typical). The output continues in the High-Z
state, and the inputs are disconnected from the
external circuit, to prevent internal signals from
affecting circuit operation. The op amp inputs are internally connected to a common mode voltage buffer and
feedback resistors. The offset is corrected (using a
digital state machine, logic and memory), and the
calibration constants are stored in memory.

Common-Mode Reference’s
When the VCAL pin is left open, the internal resistor
divider generates a VCM_INT of approximately VDD/3,
which is near the center of the input common mode
voltage range. It is recommended that an external
capacitor from VCAL to ground be added to improve
noise immunity.
When the VCAL pin is driven by an external voltage
source, which is within its specified range, the op amp
will have its input offset voltage calibrated at that common mode input voltage. Make sure that VCAL is within
its specified range.
DS22146A-page 21
MCP651/2/5
It is possible to use an external resistor voltage divider
to modify VCM_INT; see Figure 4-2. The internal circuitry
at the VCAL pin looks like 100 kΩ tied to VDD/3. The
parallel equivalent of R1 and R2 should be much
smaller than 100 kΩ to minimize differences in matching and temperature drift between the internal and
external resistors. Again, make sure that VCAL is within
its specified range.

For instance, a design goal to set VCM_INT = 0.1V when
VDD = 2.5V could be met with: R1 = 24.3 kΩ,
R2 = 1.00 kΩ and C1 = 100 nF. This will keep VCAL
within its range for any VDD, and should be close
enough to 0V for ground based applications.

Simplified Analog Input ESD
In order to prevent damage and/or improper operation
of these amplifiers, the circuit must limit the currents
(and voltages) at the input pins (see Section 1.1
“Absolute Maximum Ratings †”). Figure 4-4 shows
the recommended approach to protecting these inputs.
The internal ESD diodes prevent the input pins (VIN+
and VIN–) from going too far below ground, and the
resistors R1 and R2 limit the possible current drawn out
of the input pins. Diodes D1 and D2 prevent the input
pins (VIN+ and VIN–) from going too far above VDD, and
dump any currents onto VDD. When implemented as
shown, resistors R1 and R2 also limit the current
through D1 and D2.

The ESD protection on the inputs can be depicted as
shown in Figure 4-3. This structure was chosen to
protect the input transistors, and to minimize input bias
current (IB). The input ESD diodes clamp the inputs
when they try to go more than one diode drop below
VSS. They also clamp any voltages that go too far
above VDD; their breakdown voltage is high enough to
allow normal operation, and low enough to bypass
quick ESD events within the specified limits.

Protecting the Analog
It is also possible to connect the diodes to the left of the
resistor R1 and R2. In this case, the currents through
the diodes D1 and D2 need to be limited by some other
mechanism. The resistors then serve as in-rush current
limiters; the DC current into the input pins (VIN+ and
VIN–) should be very small.
A significant amount of current can flow out of the
inputs (through the ESD diodes) when the common
mode voltage (VCM) is below ground (VSS); see
Figure 2-15. Applications that are high impedance may
need to limit the usable voltage range.

NORMAL OPERATION
4.3.0.3
The input stage of the MCP651/2/5 op amps uses a differential PMOS input stage. It operates at low common
mode input voltage (VCM), with VCM up to VDD – 1.3V
and down to VSS – 0.3V. The input offset voltage (VOS)
is measured at VCM = VSS – 0.3V and VDD – 1.3V to
ensure proper operation. See Figure 2-6 and
Figure 2-7 for temperature effects.
When operating at very low non-inverting gains, the
output voltage is limited at the top by the VCM range
(< VDD – 1.3V); see Figure 4-5
Power Dissipation
Since the output short circuit current (ISC) is specified
at ±100 mA (typical), these op amps are capable of
both delivering and dissipating significant power. Two
common loads, and their impact on the op amp’s power
dissipation, will be discussed.
Figure 4-7 shows a resistive load (RL) with a DC output
voltage (VOUT). VL is RL’s ground point, VSS is usually
ground (0V) and IOUT is the output current. The input
currents are assumed to be negligible.

Figure 4-7 shows a capacitive load (CL), which is
driven by a sine wave with DC offset. The capacitive
load causes the op amp to output higher currents at
higher frequencies. Because the output rectifies IOUT,
the op amp’s dissipated power increases (even though
the capacitor does not dissipate power).

Improving Stability
4.4.1
4.4.2
CAPACITIVE LOADS
Driving large capacitive loads can cause stability
problems for voltage feedback op amps. As the load
capacitance increases, the feedback loop’s phase
margin decreases and the closed-loop bandwidth is
reduced. This produces gain peaking in the frequency
response, with overshoot and ringing in the step
response. See Figure 2-30. A unity gain buffer (G = +1)
is the most sensitive to capacitive loads, though all
gains show the same general behavior.
Figure 4-11 shows an op amp circuit that represents
non-inverting amplifiers (VM is a DC voltage and VP is
the input) or inverting amplifiers (VP is a DC voltage
and VM is the input). The capacitances CN and CG
represent the total capacitance at the input pins; they
include the op amp’s common mode input capacitance
(CCM), board parasitic capacitance and any capacitor
placed in parallel.
When driving large capacitive loads with these op
amps (e.g., > 20 pF when G = +1), a small series
resistor at the output (RISO in Figure 4-9) improves the
feedback loop’s phase margin (stability) by making the
output load resistive at higher frequencies. The
bandwidth will be generally lower than the bandwidth
with no capacitive load.

CG acts in parallel with RG (except for a gain of +1 V/V),
which causes an increase in gain at high frequencies.
CG also reduces the phase margin of the feedback
loop, which becomes less stable. This effect can be
reduced by either reducing CG or RF.
FIGURE 4-9:
Output Resistor, RISO
Stabilizes Large Capacitive Loads.
CN and RN form a low-pass filter that affects the signal
at VP. This filter has a single real pole at 1/(2πRNCN).
Figure 4-10 gives recommended RISO values for
different capacitive loads and gains. The x-axis is the
normalized load capacitance (CL/GN), where GN is the
circuit’s noise gain. For non-inverting gains, GN and the
Signal Gain are equal. For inverting gains, GN is
1+|Signal Gain| (e.g., -1 V/V gives GN = +2 V/V).
The largest value of RF that should be used depends
on noise gain (see GN in Section 4.4.1 “Capacitive
Loads”) and CG. Figure 4-12 shows the maximum
recommended RF for several CG values.

DS22146A-page 25
MCP651/2/5
It is also possible to add a capacitor (CF) in parallel with
RF to compensate for the de-stabilizing effect of CG.
This makes it possible to use larger values of RF. The
conditions for stability are summarized in
Equation 4-10.
EQUATION 4-10:
Given:
G N1 = 1 + R F ⁄ R G
G N2 = 1 + C G ⁄ C F
fF = 1 ⁄ ( 2 π RF CF )
f Z = f F ( G N1 ⁄ G N2 )
We need:
f F ≤ f GBWP ⁄ ( 2G N2 ) , G N1 < G N2
Use coax cables, or low inductance wiring, to route
signal and power to and from the PCB. Mutual and self
inductance of power wires is often a cause of crosstalk
and unusual behavior.

Typical Applications
4.7.1
POWER DRIVER WITH HIGH GAIN
Figure 4-13 shows a power driver with high gain
(1 + R2/R1). The MCP651/2/5 op amp’s short circuit
current makes it possible to drive significant loads. The
calibrated input offset voltage supports accurate
response at high gains. R3 should be small, and equal
to R1||R2, in order to minimize the bias current induced
offset.
f F ≤ f GBWP ⁄ ( 4G N1 ) , G N1 > G N2
4.5
Power Supply
With this family of operational amplifiers, the power
supply pin (VDD for single supply) should have a local
bypass capacitor (i.e., 0.01 µF to 0.1 µF) within 2 mm
for good high frequency performance. Surface mount,
multilayer ceramic capacitors, or their equivalent,
should be used.
These op amps require a bulk capacitor (i.e., 2.2 µF or
larger) within 50 mm to provide large, slow currents.
Tantalum capacitors, or their equivalent, may be a good
choice. This bulk capacitor can be shared with other
nearby analog parts as long as crosstalk through the
supplies does not prove to be a problem.
4.6
High Speed PCB Layout
These op amps are fast enough that a little extra care
in the PCB (Printed Circuit Board) layout can make a
significant difference in performance. Good PC board
layout techniques will help you achieve the
performance shown in the specifications and Typical
Performance Curves; it will also help you minimize
EMC (Electro-Magnetic Compatibility) issues.
Use a solid ground plane. Connect the bypass local
capacitor(s) to this plane with minimal length traces.
This cuts down inductive and capacitive crosstalk.
Separate digital from analog, low speed from high
speed, and low power from high power. This will reduce
interference.
Keep sensitive traces short and straight. Separate
them from interfering components and traces. This is
especially important for high frequency (low rise time)
signals.

DESIGN AIDS
Microchip provides the basic design aids needed for
the MCP651/2/5 family of op amps.
5.1
SPICE Macro Model
The latest SPICE macro model for the MCP651/2/5 op
amps is available on the Microchip web site at
www.microchip.com. This model is intended to be an
initial design tool that works well in the op amp’s linear
region of operation over the temperature range. See
the model file for information on its capabilities.
Bench testing is a very important part of any design and
cannot be replaced with simulations. Also, simulation
results using this macro model need to be validated by
comparing them to the data sheet specifications and
characteristic curves.
5.2
FilterLab® Software
Microchip’s FilterLab® software is an innovative
software tool that simplifies analog active filter (using
op amps) design. Available at no cost from the Microchip web site at www.microchip.com/filterlab, the Filter-Lab design tool provides full schematic diagrams of
the filter circuit with component values. It also outputs
the filter circuit in SPICE format, which can be used
with the macro model to simulate actual filter performance.
5.3
Mindi™ Circuit Designer &
Simulator
Microchip’s Mindi™ Circuit Designer & Simulator aids
in the design of various circuits useful for active filter,
amplifier and power management applications. It is a
free online circuit designer & simulator available from
the Microchip web site at www.microchip.com/mindi.
This interactive circuit designer & simulator enables
designers to quickly generate circuit diagrams, and
simulate circuits. Circuits developed using the Mindi
Circuit Designer & Simulator can be downloaded to a
personal computer or workstation.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
