The Microchip Technology Inc. MCP651/1S/2/3/4/5/9
family of high bandwidth and high slew rate 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.

Note 1:

4:
The MCP652 single, MCP653 single, MCP655 dual and MCP659 quad have their CAL/CS inputs 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.
For the MCP659 quad, there is an additional constraint. CALAD/CSAD and CALBC/CSBC can be toggled simultaneously (within a time much smaller than tCSU) to make all four op amps perform the same function simultaneously, and
the maximum tCON time is approximately doubled (8 ms). If they are toggled independently, then CALAD/CSAD
(CALBC/CSBC) cannot be allowed to toggle while op amps B and C (op amps A and D) are in Calibration mode; allow
more than the maximum tCON time (8 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.

3.1
Analog Outputs
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)
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.
2009-2014 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 (JA).

APPLICATIONS
The MCP651/1S/2/3/4/5/9 family of self-zeroed op
amps is manufactured using Microchip’s state-of-theart CMOS process. It is designed for low-cost, lowpower and high-precision applications. Its low supply
voltage, low quiescent current and wide bandwidth
makes the MCP651/1S/2/3/4/5/9 ideal for batterypowered 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 powerup 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.
While in the Low-Power mode, the quiescent current is
quite small (ISS = -3 µA, typical). The output is also 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.
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 M pull-down resistor tied to the
CAL/CS pin. If the CAL/CS pin is left floating, the
amplifier operates normally.
For the MCP655 dual and the MCP659 quad, there is
an additional constraint on toggling the two CAL/CS
pins close together; see the tCON specification in
Table 1-3. If the two pins are toggled simultaneously, or
if they are toggled separately with an adequate delay
between them (greater than tCON), then the CAL/CS
inputs are accepted as valid. If one of the two pins
toggles while the other pin’s calibration routine is in
progress, then an invalid input occurs and the result is
unpredictable.
4.1.3
INTERNAL POR
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
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 k resistor provides over-current protection for the
buffer.

MCP651/1S/2/3/4/5/9
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.
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 k tied to VDD/3. The
parallel equivalent of R1 and R2 should be much
smaller than 100 k to minimize differences in
matching and temperature drift between the internal
and external resistors. Again, make sure that VCAL is
within its specified range.

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.
Setting VCM with External
For instance, a design goal to set VCM_INT = 0.1V when
VDD = 2.5V could be met with: R1 = 24.3 k,
R2 = 1.00 k 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.

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.

The input stage of the MCP651/1S/2/3/4/5/9 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

VDD/2.

4.3.0.3
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 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).
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.

Where:

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.
The maximum ambient to junction temperature rise
(TJA) and junction temperature (TJ) can be calculated
using the maximum expected package power (PPKG),
ambient temperature (TA) and the package thermal
resistance (JA) found in Table 1-4:

Several techniques are available to reduce TJA for a

• Reduce JA
- Use another package
- Improve the PCB layout (ground plane, etc.)
- Add heat sinks and air flow
• Reduce max(PPKG)

Improving Stability
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 4-9:

Stabilizes Large Capacitive Loads.
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).

After selecting RISO for your circuit, double check the
resulting frequency response peaking and step
response overshoot. Modify RISO’s value until the
response is reasonable. Bench evaluation and
simulations with the MCP651/1S/2/3/4/5/9 SPICE
macro model are helpful.

GAIN PEAKING
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.

Amplifier with Parasitic
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.
CN and RN form a low-pass filter that affects the signal
at VP. This filter has a single real pole at 1/(2RNCN).
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.

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.

Figure 2-37 and Figure 2-38 show the small signal and
large signal step responses at G = +1 V/V. The unitygain buffer usually has RF = 0 and RG open.
Figure 2-39 and Figure 2-40 show the small signal and
large signal step responses at G = -1 V/V. Since the
noise gain is 2 V/V and CG 10 pF, the resistors were
chosen to be RF = RG = 499 and RN = 249.
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 410.

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 PCB layout
techniques will help achieve the performance shown in
the specifications and Typical Performance Curves; it
will also help minimize EMC (Electro-Magnetic Compatibility) issues.
Use a solid ground plane. Connect the bypass local
capacitor(s) to this plane with minimal length traces to
cut down inductive and capacitive crosstalk.
Separate digital from analog, low-speed from highspeed, 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.
Sometimes, it helps to place guard traces next to victim
traces. They should be on both sides of the victim
trace, and as close as possible. Connect guard traces
to ground plane at both ends, and in the middle for long
traces.
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.

POWER DRIVER WITH HIGH GAIN
Figure 4-13 shows a power driver with high gain
(1 + R2/R1). The MCP651/1S/2/3/4/5/9 op amp’s shortcircuit 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.

photo detector is a capacitive current source. The op
amp’s input Common mode capacitance (5 pF, typical)
acts in parallel with CD. RF provides enough gain to
produce 10 mV at VOUT. CF stabilizes the gain and limits the transimpedance bandwidth to about 1.1 MHz.

This circuit automatically makes the noise gains (GN)
equal, when the gains are set properly, so that the
frequency responses match well (in magnitude and in

GDM needs to be selected first.

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
