The Microchip Technology Inc. MCP6271/1R/2/3/4/5
family of operational amplifiers (op amps) provide wide
bandwidth for the current. This family has a 2 MHz
Gain Bandwidth Product (GBWP) and a 65° Phase
Margin. This family also operates from a single supply
voltage as low as 2.0V, while drawing 170 µA (typ.)
quiescent current. The MCP6271/1R/2/3/4/5 supports
rail-to-rail input and output swing, with a common mode
input voltage range of VDD + 300 mV to VSS – 300 mV.
This family of op amps is designed with Microchip’s
advanced CMOS process.
Gain Bandwidth Product: 2 MHz (typ.)
Supply Current: IQ = 170 µA (typ.)
Supply Voltage: 2.0V to 5.5V
Rail-to-Rail Input/Output
Extended Temperature Range: –40°C to +125°C
Available in Single, Dual and Quad Packages
Parts with Chip Select (CS)
- Single (MCP6273)
- Dual (MCP6275)
The MCP6275 has a Chip Select input (CS) for dual op
amps in an 8-pin package and is manufactured by
cascading two op amps (the output of op amp A
connected to the non-inverting input of op amp B). The
CS input puts the device in low power mode.

Power Supply (VSS and VDD)
The positive power supply (VDD) is 2.0V 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 a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the VDD pin. These parts need
to use a bulk capacitor (within 100 mm), which can be
shared with nearby analog parts.

APPLICATION INFORMATION
The MCP6271/1R/2/3/4/5 family of op amps is
manufactured using Microchip’s state of the art CMOS
process, specifically designed for low cost, low power
and general purpose applications. The low supply
voltage, low quiescent current and wide bandwidth
make the MCP6271/1R/2/3/4/5 ideal for battery
powered applications.
4.1
Rail-to-Rail Inputs
The input stage of the MCP6271/1R/2/3/4/5 op amps
uses two differential CMOS input stages in parallel.
One operates at low common mode input voltage (VCM,
which is aproximately equal to VIN+ and VIN– in normal
operation) and the other at high VCM. With this topology, the input operates with VCM up to 0.3V past either
supply rail (see Figure 2-7 and Figure 2-10). The input
offset voltage (VOS) is measured at VCM = VSS – 0.3V
and VDD + 0.3V to ensure proper operation.
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 Absolute Maximum Ratings † at the beginning of Section 1.0 “Electrical Characteristics”). Figure 4-2 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.
VDD
D1
V1
R1
The transition between the two input stage occurs
when VCM ≈ VDD – 1.1V (see Figure 2-3 and Figure 26). For the best distortion and gain linearity, with noninverting gains, avoid this region of operation.
4.1.1
The ESD protection on the inputs can be depicted as
shown in Figure 4-1. 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 2-32. Applications that are high impedance may
need to limit the useable voltage range.

4.3
Capacitive Loads
4.4
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. A unity gain buffer (G = +1) is the most
sensitive to capacitive loads, though all gains show the
same general behavior.
When driving large capacitive loads with these op
amps (e.g., > 100 pF when G = +1), a small series
resistor at the output (RISO in Figure 4-3) 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.

MCP6273/5 Chip Select (CS)
The MCP6273 and MCP6275 are single and dual op
amps with Chip Select (CS), respectively. When CS is
pulled high, the supply current drops to 0.7 µA (typ.)
and flows through the CS pin to VSS. When this
happens, the amplifier output is put into a high
impedance state. By pulling CS low, the amplifier is
enabled. The CS pin has a 5 MΩ (typ.) pull-down
resistor connected to VSS, so it will go low if the CS pin
is left floating. Figure 1-1 shows the output voltage and
supply current response to a CS pulse.
4.5
Cascaded Dual Op Amps
(MCP6275)
The MCP6275 is a dual op amp with Chip Select (CS).
The Chip Select input is available on what would be the
non-inverting input of a standard dual op amp (pin 5).
This pin is available because the output of op amp A
connects to the non-inverting input of op amp B, as
shown in Figure 4-5. The Chip Select input, which can
be connected to a microcontroller I/O line, puts the
device in low power mode. Refer to Section 4.4
“MCP6273/5 Chip Select (CS)”.
Figure 4-4 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 common mode input range of these op amps is
specified in the data sheet as VSS – 300 mV and
VDD + 300 mV. However, since the output of op amp A
is limited to VOL and VOH (20 mV from the rails with a
10 kΩ load), the non-inverting input range of op amp B
is limited to the common mode input range of
VSS + 20 mV and VDD – 20 mV.
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 MCP6271/1R/2/3/4/5 SPICE
macro model are helpful.

Unused Amplifiers

An unused op amp in a quad package (MCP6274)
should be configured as shown in Figure 4-6. These
circuits prevent the output from toggling and causing
crosstalk. In Circuit A, R1 and R2 produce a voltage
within its output voltage range (VOH, VOL). The op amp
buffers this voltage, which can be used elsewhere in
the circuit. Circuit B uses the minimum number of
components and operates as a comparator.

Supply Bypass
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. It also needs a
bulk capacitor (i.e., 1 µF or larger) within 100 mm to
provide large, slow currents. This bulk capacitor can be
shared with nearby analog parts.

Example Guard Ring Layout
For Inverting Gain and Transimpedance
Amplifiers (convert current to voltage, such as
photo detectors):
a) Connect the guard ring to the non-inverting
input pin (VIN+). This biases the guard ring
to the same reference voltage as the op
amp (e.g., VDD/2 or ground).
b) Connect the inverting pin (VIN–) to the input
with a wire that does not touch the PCB
surface.
Non-inverting Gain and Unity Gain Buffer:
a) Connect the non-inverting pin (VIN+) to the
input with a wire that does not touch the
PCB surface.
b) Connect the guard ring to the inverting input
pin (VIN–). This biases the guard ring to the
common mode input voltage.
PCB Surface Leakage
In applications where low input bias current is critical,
Printed Circuit Board (PCB) surface leakage effects
need to be considered. Surface leakage is caused by
humidity, dust or other contamination on the board.
Under low humidity conditions, a typical resistance
between nearby traces is 1012Ω. A 5V difference would
cause 5 pA of current to flow. This is greater than the
MCP6271/1R/2/3/4/5 family’s bias current at 25°C
(1 pA, typ.).
The easiest way to reduce surface leakage is to use a
guard ring around sensitive pins (or traces). The guard
ring is biased at the same voltage as the sensitive pin.
An example of this type of layout is illustrated in
Figure 4-7.

ACTIVE FULL-WAVE RECTIFIER
The MCP6271/1R/2/3/4/5 family of amplifiers can be
used in applications such as an Active Full-Wave
Rectifier or an Absolute Value circuit, as shown in
Figure 4-8. The amplifier and feedback loops in this
active voltage rectifier circuit eliminate the diode drop
problem that exists in a passive voltage rectifier. This
circuit behaves as a follower (the output follows the
input) as long as the input signal is more positive than
the reference voltage. If the input signal is more
negative than the reference voltage, however, the
circuit behaves as an inverting amplifier. Therefore, the
output voltage will always be above the reference
voltage, regardless of the input signal.
LOSSY NON-INVERTING
INTEGRATOR
The non-inverting integrator shown in Figure 4-9 is
easy to build. It saves one op amp over the typical
Miller integrator plus inverting amplifier configuration.
The phase accuracy of this integrator depends on the
matching of the input and feedback resistor-capacitor
time constants. RF makes this a lossy integrator (it has
finite gain at DC), and makes this integrator stable by
itself.

MCP6275 eliminates the added cost and space in a
battery powered application by using two single op
amps with Chip Select (CS) lines or a 10-pin device
with one CS line for both op amps. Since the two op
amps are internally cascaded, this device cannot be
used in circuits that require active or passive elements
between the two op amps. However, there are several
applications where this op amp configuration with a CS
line becomes suitable. The circuits below show
possible applications for this device.
4.9.3.1
R3
With the cascaded op amp configuration, op amp B can
be used to isolate the load from op amp A. In
applications where op amp A is driving capacitive or
low resistive loads in the feedback loop (such as an
integrator or filter circuit) the op amp may not have
sufficient source current to drive the load. In this case,
op amp B can be used as a buffer.

Cascaded Gain Circuit
Difference Amplifier
Figure 4-12 shows op amp A configured as a difference
amplifier with Chip Select. In this configuration, it is
recommended that well matched resistors (e.g., 0.1%)
be used to increase the Common Mode Rejection Ratio
(CMRR). Op amp B can be used to provide additional
gain and isolate the load from the difference amplifier.

Isolating the Load with a
Cascaded Gain
Figure 4-11 shows a cascaded gain circuit configuration with Chip Select. Op amps A and B are configured
in a non-inverting amplifier configuration. In this
configuration, it is important to note that the input offset
voltage of op amp A is amplified by the gain of op amp
A and B, as shown below:
V OUT = V IN G A G B + V OSA G A G B + V OSB G B
Where:

Inverting Integrator with Active
Compensation and Chip Select
Figure 4-13 uses an active compensator (op amp B) to
compensate for the non-ideal op amp characteristics
introduced at higher frequencies. This circuit uses
op amp B as a unity gain buffer to isolate the
integration capacitor C1 from op amp A and drives the
capacitor with a low impedance source. Since both op
amps are matched very well, they provide a high quality
integrator.

Therefore, it is recommended that you set most of the

Low-Pass filter with Chip Select
The low-pass filter shown in Figure 4-16 does not
require external capacitors and uses only three
external resistors; the op amp’s GBWP sets the corner
frequency. R1 and R2 are used to set the circuit gain. R3
is used to set the Q. To avoid gain peaking in the
frequency response, Q needs to be low (lower values
need to be selected for R3). Note that the amplifier
bandwidth varies greatly over temperature and
process. This configuration, however, provides a low
cost solution for applications with high bandwidth
requirements.

DESIGN TOOLS
Microchip provides the basic design tools needed for
the MCP6271/1R/2/3/4/5 family of op amps.
5.1
SPICE Macro Model
The latest SPICE macro model for the
MCP6271/1R/2/3/4/5 op amps is available on our 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 at room temperature. See the
macro 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 tool that
simplifies analog active filter (using op amps) design. It
is available free of charge from our web site at
www.microchip.com. The FilterLab software 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.
