Negative Power Supply
3.3
Power Supply (VSS and VDD)
The positive power supply (VDD) is 1.8V 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 can
share a bulk capacitor (typically 1 µF to 100 µF) with
other nearby analog parts; it needs to be within 100 mm
of the VDD pin.

APPLICATION INFORMATION
–
The MCP6241/2/4 family of op amps is manufactured
using Microchip’s state-of-the-art CMOS process and
is specifically designed for low-power and generalpurpose applications. The low supply voltage, low
quiescent current and wide bandwidth makes the
MCP6241/2/4 ideal for battery-powered applications.

Rail-to-Rail Inputs
The MCP6241/2/4 op amps are designed to prevent
phase reversal when the input pins exceed the supply
voltages. Figure 4-1 shows the input voltage exceeding
the supply voltage without any phase reversal.

Rail-to-Rail Output
The output voltage range of the MCP6241/2/4 op amps
is VDD – 35 mV (max.) and VSS + 35 mV (min.) when
RL = 10 kΩ is connected to VDD/2 and VDD = 5.5V.
Refer to Figure 2-14 for more information.

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, but all gains show the
same general behavior.

Time (1 ms/div)
FIGURE 4-1:
Phase Reversal.
The MCP6241/2/4 Show No
The input stage of the MCP6241/2/4 op amps use two
differential input stages in parallel. One operates at low
common mode input voltage (VCM) and the other at
high VCM. With this topology, the device operates with
VCM up to 300 mV above VDD and 300 mV below VSS.
The Input Offset Voltage is measured at
VCM = VSS – 300 mV and VDD + 300 mV to ensure
proper operation.
Input voltages that exceed the input voltage range
(VSS – 0.3V to VDD + 0.3V at 25°C) can cause
excessive current to flow into or out of the input pins.
Current beyond ±2 mA can cause reliability problems.
Applications that exceed this rating must be externally
limited with a resistor, as shown in Figure 4-2.
Capacitive Loads
When driving large capacitive loads with these op
amps (e.g., > 70 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.

stabilizes large capacitive loads.
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).

In applications where low input bias current is critical,
PCB (printed circuit board) 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
MCP6241/2/4 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 shown in
Figure 4-6.

After selecting RISO for your circuit, double-check the
resulting frequency response peaking and step
response overshoot. Evaluation on the bench and
simulations with the MCP6241/2/4 SPICE macro
model are very helpful. Modify RISO’s value until the
response is reasonable.

Supply Bypass
With this op amp, 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 highfrequency 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 nearby analog parts.

Unused Op Amps
An unused op amp in a quad package (MCP6244)
should be configured as shown in Figure 4-5. Both
circuits prevent the output from toggling and causing
crosstalk. Circuit A can use any reference voltage
between the supplies, provides a buffered DC voltage,
and minimizes the supply current draw of the unused
op amp. Circuit B minimizes the number of
components, but may draw a little more supply current
for the unused op amp.

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 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
4.7.1
MATCHING THE IMPEDANCE AT
THE INPUTS
To minimize the effect of offset voltage in an amplifier
circuit, the impedances at the inverting and noninverting inputs need to be matched. This is done by
choosing the circuit resistor values so that the total
resistance at each input is the same. Figure 4-7 shows
a summing amplifier circuit.
COMPENSATING FOR THE
PARASITIC CAPACITANCE
In analog circuit design, the PCB parasitic capacitance
can compromise the circuit behavior; Figure 4-8 shows
a typical scenario. If the input of an amplifier sees
parasitic capacitance of several picofarad (CPARA,
which includes the common mode capacitance of 6 pF,
typical) and large RF and RG , the frequency response
of the circuit will include a zero. This parasitic zero
introduces gain peaking and can cause circuit
instability.

FIGURE 4-7:
Summing Amplifier Circuit.
To match the inputs, set all voltage sources to ground
and calculate the total resistance at the input nodes. In
this summing amplifier circuit, the resistance at the
inverting input is calculated by setting VIN1, VIN2 and
VOUT to ground. In this case, RG1, RG2 and RF are in
parallel. The total resistance at the inverting input is:
1
R VIN – = --------------------------------------------1

⎛ ----------------- ------⎞
⎝ R G1 + R G2 + RF⎠
RG
C F = CPARA • ------RF
FIGURE 4-8:
Effect of Parasitic
Capacitance at the Input.
One solution is to use smaller resistor values to push
the zero to a higher frequency. Another solution is to
compensate by introducing a pole at the point at which
the zero occurs. This can be done by adding CF in
parallel with the feedback resistor (RF). CF needs to be
selected so that the ratio CPARA:CF is equal to the ratio
of RF:RG .
Where:
RVIN– = total resistance at the inverting input
At the non-inverting input, VDD is the only voltage
source. When VDD is set to ground, both RX and RY are
in parallel. The total resistance at the non-inverting
input is:
1
R VIN + = ------------------------- + R Z
1
1
⎛ -----+ ------⎞
⎝ RX RY⎠
Where:
RVIN+ = total resistance at the inverting
input
To minimize offset voltage and increase circuit
accuracy, the resistor values need to meet the
condition:
R VIN + = R VIN –

DESIGN TOOLS
Microchip provides the basic design tools needed for
the MCP6241/2/4 family of op amps.
5.1
SPICE Macro Model
The latest SPICE macro model for the MCP6241/2/4 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.
Available at no cost from our web site at
www.microchip.com, 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.
