Test Circuits
The circuit used for most DC and AC tests is shown in
Figure 1-1. 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.

Power Supply Pin (VDD, VSS)
The positive power supply (VDD) is 1.8V to 6.0V higher
than the negative power supply (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.

APPLICATION INFORMATION
VDD
The MCP6401/1R/1U family of op amps is
manufactured using Microchip’s state-of-the-art CMOS
process and is specifically designed for low-power,
high precision applications.

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 voltage that go too far above
VDD; their breakdown voltage is high enough to allow
normal operation and low enough to bypass ESD
events within the specified limits.

Inputs.
Simplified Analog Input ESD
In order to prevent damage and/or improper operation
of these op amps, the circuit they are in must limit the
voltages and currents at the VIN+ and VIN- 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.
When implemented as shown, resistors R1 and R2 also
limit the current through D1 and D2.
© 2009 Microchip Technology Inc.
Protecting the Analog
It is also possible to connect the diodes to the left of the
resistors 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 currents into the input pins (VIN+ and
VIN-) should be very small. A significant amount of
current can flow out of the inputs when the common
mode voltage (VCM) is below ground (VSS). (See
Figure 2-32).

PHASE REVERSAL
The MCP6401/1R/1U op amps are designed to prevent
phase reversal when the input pins exceed the supply
voltages. Figure 2-30 shows the input voltage
exceeding the supply voltage without any phase
reversal.
4.1.2

NORMAL OPERATION
The input stage of the MCP6401/1R/1U 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. (See Figure 2-11). The input
offset voltage is measured at VCM = VSS – 0.3V and
VDD + 0.3V to ensure proper operation.
The transition between the input stages occurs when
VCM is near VDD – 1.1V (See Figures 2-3 and 2-4). For
the best distortion performance and gain linearity, with
non-inverting gains, avoid this region of operation.
4.2
Rail-to-Rail Output
The output voltage range of the MCP6401/1R/1U op
amps is VSS + 20 mV (minimum) and VDD – 20 mV
(maximum) when RL = 10 kΩ is connected to VDD/2
and VDD = 6.0V. Refer to Figures 2-23 and 2-24 for
more information.
DS22229A-page 13
MCP6401/1R/1U
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. While a unity-gain buffer (G = +1 V/V) is the
most sensitive to capacitive loads, all gains show the
same general behavior.
When driving large capacitive loads with these op
amps (e.g., > 100 pF when G = +1 V/V), 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 capacitance load.

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 can be shared
with other analog parts.
4.5
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
MCP6401/1R/1U family’s bias current at +25°C
(±1.0 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 4-5.

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).

After selecting RISO for your circuit, double-check the

response is reasonable. Bench evaluation and
simulations with the MCP6401/1R/1U SPICE macro
model are very helpful.

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
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.

Application Circuits

PRECISION HALF-WAVE
RECTIFIER
The precision half-wave rectifier, which is also known
as a super diode, is a configuration obtained with an
operational amplifier in order to have a circuit behaving
like an ideal diode and rectifier. It effectively cancels the
forward voltage drop of the diode so that very low level
signals can still be rectified with minimal error. This can
be useful for high-precision signal processing. The
MCP6401/1R/1U op amps have high input impedance,
low input bias current and rail-to-rail input/output, which
makes this device suitable for precision rectifier
applications.
Figure 4-6 shows a precision half-wave rectifier and its
transfer characteristic. The rectifier’s input impedance
is determined by the input resistor R1. To avoid loading
effect, it must be driven from a low impedance source.
When VIN is greater than zero, D1 is OFF and D2 is ON,
VOUT is zero. When VIN is less than zero, D1 is ON and
D2 is OFF, and VOUT is the VIN with an amplification of
-R2/R1.
BATTERY CURRENT SENSING
The MCP6401/1R/1U 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 low quiescent current
(45 µA, typical) helps prolong battery life, and the
rail-to-rail output supports detection of low currents.
Figure 4-7 shows a high side battery current sensor
circuit. The 10Ω resistor is sized to minimize power
losses. The battery current (IDD) through the 10Ω
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. The output of the op amp will
also be below VDD, which is within its Maximum Output
Voltage Swing specification.

The MCP6401/1R/1U op amps are well suited for
conditioning sensor signals in battery-powered
applications. Figure 4-8 shows a two op amp
instrumentation amplifier, using the MCP6401, that
works well for applications requiring rejection of
common mode noise at higher gains. The reference
voltage (VREF) is supplied by a low impedance source.
In single supply applications, VREF is typically VDD/2.

DESIGN AIDS
Microchip provides the basic design tools needed for
the MCP6401/1R/1U family of op amps.
5.1
SPICE Macro Model
The latest SPICE macro model for the MCP6401/1R/
1U op amp is available on the Microchip web site at
www.microchip.com. The model was written and tested
in official Orcad (Cadence) owned PSPICE. For the
other simulators, it may require translation.
The model covers a wide aspect of the op amp's
electrical specifications. Not only does the model cover
voltage, current, and resistance of the op amp, but it
also covers the temperature and noise effects on the
behavior of the op amp. The model has not been
verified outside of the specification range listed in the
op amp data sheet. The model behaviors under these
conditions cannot be guaranteed that it will match the
actual op amp performance.
Moreover, the model is intended to be an initial design
tool. 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
5.4
Microchip Advanced Part Selector
(MAPS)
MAPS is a software tool that helps semiconductor
professionals efficiently identify Microchip devices that
fit a particular design requirement. Available at no cost
from the Microchip website at www.microchip.com/
maps, the MAPS is an overall selection tool for
Microchip’s product portfolio that includes Analog,
Memory, MCUs and DSCs. Using this tool you can
define a filter to sort features for a parametric search of
devices and export side-by-side technical comparison
reports. Helpful links are also provided for Datasheets,
Purchase, and Sampling of Microchip parts.

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.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
