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 (refer to 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 output pins are low-impedance voltage sources.
3.2
Analog Inputs
The non-inverting and inverting inputs are
high-impedance CMOS inputs with low bias currents.
3.3
Power Supply Pins
The positive power supply (VDD) is 3.5V to 12V higher
than the negative power supply (VSS). For normal
operation, the other pins are at voltages between VSS
and VDD.
Typically, these parts can be used in single-supply
operation or dual-supply operation. Also, VDD will need
bypass capacitors.
3.4
Exposed Thermal Pad (EP)
There is an internal electrical 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).

PHASE REVERSAL
The MCP6H81/2/4 op amps are designed to prevent
phase reversal when the input pins exceed the supply
voltages. Figure 2-36 shows the input voltage
exceeding the supply voltage without any phase
reversal.
4.1.2
INPUT VOLTAGE LIMITS
In order to prevent damage and/or improper operation
of these amplifiers, the circuit must limit the voltages at
the input pins (see Section 1.1 “Absolute Maximum
Ratings †”).
The ESD protection on the inputs can be depicted as
shown in Figure 4-1. This structure was chosen to
protect the input transistors against many (but not all)
overvoltage conditions, and to minimize the input bias
current (IB).
FIGURE 4-2:
Inputs.
Protecting the Analog
A significant amount of current can flow out of the
inputs when the common mode voltage (VCM) is below
ground (VSS), as shown in Figure 2-38.
4.1.3
INPUT CURRENT LIMITS
In order to prevent damage and/or improper operation
of these amplifiers, the circuit must limit the currents
into the input pins (see Section 1.1 “Absolute
Maximum Ratings †”).
Figure 4-3 shows one approach to protecting these
inputs. The resistors R1 and R2 limit the possible
currents in or out of the input pins (and the ESD diodes,
D1 and D2). The diode currents will go through either
VDD or VSS.

Simplified Analog Input ESD
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 well above VDD. Their
breakdown voltage is high enough to allow normal
operation, but not low enough to protect against slow
overvoltage (beyond VDD) events. Very fast ESD
events (that meet the specification) are limited so that
damage does not occur.
In some applications, it may be necessary to prevent
excessive voltages from reaching the op amp inputs;
Figure 4-2 shows one approach to protecting these
inputs.

Protecting the Analog
NORMAL OPERATION
The inputs of the MCP6H81/2/4 op amps connect to a
differential PMOS input stage. It operates at a low
common mode input voltage (VCM), including ground.
With this topology, the device operates with a VCM up
to VDD – 2.5V and 0.3V below VSS (refer to Figures 2-3
through 2-5). The input offset voltage is measured at
VCM = VSS – 0.3V and VDD – 2.5V to ensure proper
operation.
For a unity gain buffer, VIN must be maintained below
VDD – 2.5V for correct operation.

Rail-to-Rail Output
1000
The output voltage range of the MCP6H81/2/4 op amps
is 0.020V (typical) and 11.980V (typical) when
RL = 10 k is connected to VDD/2 and VDD = 12V.
Refer to Figures 2-24 through 2-29 for more
information.
4.3
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. While a unity-gain buffer (G = +1V/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 = + 1V/V), a small series
resistor at the output (RISO in Figure 4-4) improves the
feedback loop’s phase margin (stability) by making the
output load resistive at higher frequencies. The
bandwidth will generally be 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.

Figure 4-5 gives the 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., -1V/V gives GN = +2V/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 MCP6H81/2/4 SPICE macro
model are helpful.

Unused Op Amps
An unused op amp in a quad package (MCP6H84)
should be configured as shown in Figure 4-6. These
circuits prevent the output from toggling and causing
crosstalk. Circuit A sets the op amp at its minimum
noise gain. The resistor divider produces any desired
reference voltage within the output voltage range of the
op amp, and 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.

PCB Surface Leakage
4.7
In applications where low input bias current is critical,
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
1012. A 15V difference would cause 15 pA of current
to flow, which is greater than the MCP6H81/2/4 family’s
bias current at +25°C (10 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 4-7.

4.7.1
Application Circuits
DIFFERENCE AMPLIFIER
The MCP6H81/2/4 op amps can be used in current
sensing applications. Figure 4-8 shows a resistor
(RSEN) that converts the sensor current (ISEN) to
voltage, as well as a difference amplifier that amplifies
the voltage across the resistor while rejecting common
mode noise. R1 and R2 must be well matched to obtain
an acceptable Common Mode Rejection Ratio
(CMRR). Moreover, RSEN should be much smaller than
R1 and R2 in order to minimize the resistive loading of
the source.
To ensure proper operation, the op amp common mode
input voltage must be kept within the allowed range.
The reference voltage (VREF) is supplied by a
low-impedance source. In single-supply applications,
VREF is typically VDD/2.

ACTIVE FULL-WAVE RECTIFIER
The MCP6H81/2/4 family of op amps can be used in
applications such as an active full-wave rectifier, as
shown in Figure 4-9. 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 voltage 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 with a
Gain = -1V/V. Therefore, the output voltage will always
be above the reference voltage, regardless of the input
signal. The reference voltage (VREF) is supplied by a
low-impedance source. In single-supply applications,
VREF is typically VDD/2.
4.7.3
The MCP6H81/2/4 family of op amps can be used in
function generation applications, such as triangle
waves generator, as shown in Figure 4-10.
The triangle waves generator consists of an integrator
and one comparator, connected in a positive feedback
loop. This approach is based on the simple fact that
integration of a constant voltage results in a linear
ramp. The op amp is configured as an integrator using
R1 and C1 to provide the triangular output and the
Schmitt triggers are designed with R2 and R3 to change
the state corresponding to the desired peak voltages of
the triangular wave output. The reference voltage
(VREF) is supplied by a low-impedance source. In
single-supply applications, VREF is typically VDD/2.

DESIGN AIDS
Microchip Technology Inc. provides the basic design
tools needed for the MCP6H81/2/4 family of op amps.
5.1
SPICE Macro Model
The latest SPICE macro model for the MCP6H81/2/4
op amp is available on the Microchip web site at
www.microchip.com. The model was written and tested
in PSpice, owned by Orcad (Cadence®). For other
simulators, translation may be required.
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 the specification range listed in the op
amp data sheet. The model behaviors under these
conditions cannot be guaranteed to 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.

MAPS (Microchip Advanced Part
Selector)
MAPS is a software tool that helps semiconductor
professionals efficiently identify Microchip devices that
fit a particular design requirement. Available at no cost
on the Microchip web site at www.microchip.com/maps,

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.”
