Analog Inputs
The non-inverting and inverting inputs are
high-impedance CMOS inputs with low bias currents.
3.3
CS Digital Input

Power Supply Pins
The positive power supply pin (VDD) is 1.4V to 6.0V
higher than the negative power supply pin (VSS). For
normal operation, the other pins are at voltages
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.
This is a CMOS, Schmitt-triggered input that places the
part into a low power mode of operation.

APPLICATIONS INFORMATION
The MCP6141/2/3/4 family of op amps is manufactured
using Microchip’s state of the art CMOS process These
op amps are stable for gains of 10 V/V and higher. They
are suitable for a wide range of general purpose, low
power applications.
See Microchip’s related MCP6041/2/3/4 family of op
amps for applications needing unity gain stability.

INPUT VOLTAGE AND CURRENT
LIMITS
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.

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 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

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 2-33. Applications that are high impedance may
need to limit the usable voltage range.

PHASE REVERSAL
The MCP6141/2/3/4 op amps are designed to not
exhibit phase inversion when the input pins exceed the
supply voltages. Figure 2-10 shows an input voltage
exceeding both supplies with no phase inversion.

NORMAL OPERATION
The input stage of the MCP6141/2/3/4 op amps uses
two differential input stages in parallel. One operates at
a low common mode input voltage (VCM), while the
other operates at a high VCM. With this topology, the
device operates with a VCM up to 300 mV above VDD
and 300 mV below VSS. The input offset voltage is
measured at VCM = VSS – 0.3V and VDD + 0.3V to
ensure proper operation.
There are two transitions in input behavior as VCM is
changed. The first occurs, when VCM is near
VSS + 0.4V, and the second occurs when VCM is near
VDD – 0.5V (see Figure 2-3 and Figure 2-6). For the
best distortion performance with non-inverting gains,
avoid these regions of operation.
DS21668D-page 15
MCP6141/2/3/4
4.2
Rail-to-Rail Output
There are two specifications that describe the output
swing capability of the MCP6141/2/3/4 family of op
amps. The first specification (Maximum Output Voltage
Swing) defines the absolute maximum swing that can
be achieved under the specified load condition. Thus,
the output voltage swings to within 10 mV of either
supply rail with a 50 kΩ load to VDD/2. Figure 2-10
shows how the output voltage is limited when the input
goes beyond the linear region of operation.
The second specification that describes the output
swing capability of these amplifiers is the Linear Output
Voltage Range. This specification defines the
maximum output swing that can be achieved while the
amplifier still operates in its linear region. To verify
linear operation in this range, the large signal DC
Open-Loop Gain (AOL) is measured at points inside the
supply rails. The measurement must meet the specified
AOL condition in the specification table.
4.3
Output Loads and Battery Life
The MCP6141/2/3/4 op amp family has outstanding
quiescent current, which supports battery-powered
applications. There is minimal quiescent current
glitching when Chip Select (CS) is raised or lowered.
This prevents excessive current draw, and reduced
battery life, when the part is turned off or on.
Heavy resistive loads at the output can cause
excessive battery drain. Driving a DC voltage of 2.5V
across a 100 kΩ load resistor will cause the supply
current to increase by 25 µA, depleting the battery 43
times as fast as IQ (0.6 µA, typical) alone.
High frequency signals (fast edge rate) across
capacitive loads will also significantly increase supply
current. For instance, a 0.1 µF capacitor at the output
presents an AC impedance of 15.9 kΩ (1/2πfC) to a
100 Hz sinewave. It can be shown that the average
power drawn from the battery by a 5.0 VP-P sinewave
(1.77 Vrms), under these conditions, is:
EQUATION 4-1:
PSupply = (VDD - VSS) (IQ + VL(p-p) f CL )
= (5V)(0.6 µA + 5.0Vp-p · 100Hz · 0.1µF)
= 3.0 µW + 50 µW
This will drain the battery 18 times as fast as IQ alone.
DS21668D-page 16
4.4
Stability
4.4.1
NOISE GAIN
The MCP6141/2/3/4 op amp family is designed to give
high bandwidth and slew rate for circuits with high noise
gain (GN) or signal gain. Low gain applications should
be realized using the MCP6041/2/3/4 op amp family;
this simplifies design and implementation issues.
Noise gain is defined to be the gain from a voltage
source at the non-inverting input to the output when all
other voltage sources are zeroed (shorted out). Noise
gain is independent of signal gain and depends only on
components in the feedback loop. The amplifier circuits
in Figure 4-3 and Figure 4-4 have their noise gain
calculated as follows:
EQUATION 4-2:
RF
G N = 1 + ------- ≥ 10 V/V
RG
In order for the amplifiers to be stable, the noise gain
should meet the specified minimum noise gain. Note
that a noise gain of GN = +10 V/V corresponds to a
non-inverting signal gain of G = +10 V/V, or to an
inverting signal gain of G = -9 V/V.

MCP6141/2/3/4
Figure 4-5 shows three example circuits that are
unstable when used with the MCP6141/2/3/4 family.
The unity gain buffer and low gain amplifier
(non-inverting or inverting) are at gains that are too low
for stability (see Equation 4-2).The Miller integrator’s
capacitor makes it reach unity gain at high frequencies,
causing instability.
Note:
The three circuits shown in Figure 4-5 are
not to be used with the MCP6141/2/3/4 op
amps. They are included for illustrative
purposes only.
When driving large capacitive loads with these op
amps (e.g., > 60 pF when G = +10), a small series
resistor at the output (RISO in Figure 4-6) 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.

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. A unity gain buffer (G = +1) is the most
sensitive to capacitive loads, though all gains show the
same general behavior.
© 2009 Microchip Technology Inc.
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 MCP6141/2/3/4 SPICE macro
model are helpful.
4.5
MCP6143 Chip Select
The MCP6143 is a single op amp with Chip Select
(CS). When CS is pulled high, the supply current drops
to 50 nA (typical) 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. If the CS pin is left floating, the amplifier will
not operate properly. Figure 1-1 shows the output
voltage and supply current response to a CS pulse.
DS21668D-page 17
MCP6141/2/3/4
4.6
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 can use a bulk
capacitor (i.e., 1 µF or larger) within 100 mm to provide
large, slow currents. This bulk capacitor is not required
for most applications and can be shared with other
nearby analog parts.

An unused op amp in a quad package (MCP6144)

circuits prevent the output from toggling and causing
crosstalk.
Circuits A sets the op amp near its minimum noise gain.
The resistor divider produces any desired reference
voltage within the output voltage range of the op amp;
the op amp buffers that reference voltage. Circuit B
uses the minimum number of components and
operates as a comparator, but it may draw more
current.

Example Guard Ring Layout
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.
Inverting Gain and Transimpedance Gain
(convert current to voltage, such as photo
detectors) amplifiers:
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.

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, which is greater than the
MCP6141/2/3/4 family’s bias current at +25°C (1 pA,
typical).
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 shown in
Figure 4-9.

BATTERY CURRENT SENSING
The MCP6141/2/3/4 op amps’ Common Mode Input
Range, which goes 0.3V beyond both supply rails,
supports their use in high side and low side battery
current sensing applications. The very low quiescent
current (0.6 µA, typical) help prolong battery life, and
the rail-to-rail output supports detection low currents.
Figure 4-10 shows a high side battery current sensor
circuit. The 1 kΩ resistor is sized to minimize power
losses. The battery current (IDD) through the 1 kΩ
resistor causes its top terminal to be more negative
than the bottom terminal. This keeps the common
mode input voltage of the op amp below VDD, which is
within its allowed range. When no current is flowing, the
output will be at its Maximum Output Voltage Swing
(VOH), which is virtually at VDD.
.
IDD
INVERTING SUMMING AMPLIFIER
The MCP6141/2/3/4 op amp is well suited for the
inverting summing amplifier shown in Figure 4-11 when
the resistors at the input (R1, R2, and R3) make the
noise gain at least 10 V/V. The output voltage (VOUT) is
a weighted sum of the inputs (V1, V2, and V3), and is
shifted by the VREF input. The necessary calculations
follow in Equation 4-3.

DESIGN AIDS
Microchip provides the basic design tools needed for
the MCP6141/2/3/4 family of op amps.
5.1
SPICE Macro Model
The latest SPICE macro model for the MCP6141/2/3/4
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
FilterLab 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™ Simulation Tool
Microchip’s Mindi™ simulation tool aids in the design of
various circuits useful for active filter, amplifier and
power-management applications. It is a free online
simulation tool available from the Microchip web site at
www.microchip.com/mindi. This interactive simulator
enables designers to quickly generate circuit diagrams,
simulate circuits. Circuits developed using the Mindi
simulation tool 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
