Test Circuit
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 Pins
The analog output pins (VOUT) are low-impedance
voltage sources.
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 between VSS and VDD.
3.2
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.
Analog Inputs
The non-inverting and inverting inputs (VIN+, VIN–, …)
are high-impedance CMOS inputs with low bias
currents.

APPLICATION INFORMATION
The MCP6L01/1R/1U/2/4 family of op amps is manufactured using Microchip’s state of the art CMOS
process. It is designed for low cost, low power and
general purpose applications. The low supply voltage,
low quiescent current and wide bandwidth makes the
MCP6L01/1R/1U/2/4 ideal for battery-powered
applications. This device has high phase margin, which
makes it stable for larger capacitive load applications.
4.1
Rail-to-Rail Inputs
4.1.1
PHASE REVERSAL
The MCP6L01/1R/1U/2/4 op amps are designed to
prevent phase inversion when the input pins exceed
the supply voltages. Figure 2-10 shows an input
voltage exceeding both supplies without any phase
reversal.
4.1.2
INPUT VOLTAGE AND CURRENT
LIMITS
In order to prevent damage and/or improper operation
of these amplifiers, the circuit they are in must limit the
currents (and voltages) at the input pins (see
Section 1.1 “Absolute Maximum Ratings †”).
Figure 4-1 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.

MCP6L0X
V2
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 2-7. Applications that are high impedance may
need to limit the usable voltage range.
4.1.3
NORMAL OPERATION
The input stage of the MCP6L01/1R/1U/2/4 op amps
use two differential CMOS input stages in parallel. One
operates at low common mode input voltage (VCM),
while the other operates at high VCM. WIth this
topology, and at room temperature, the device
operates with VCM up to 0.3V above VDD and 0.3V
below VSS (typically at +25°C).
The transition between the two input stages occurs
when VCM = VDD – 1.1V. For the best distortion and
gain linearity, with non-inverting gains, avoid this region
of operation.
4.2
Rail-to-Rail Output
The output voltage range of the MCP6L01/1R/1U/2/4
op amps is VDD – 35 mV (minimum) and VSS + 35 mV
(maximum) when RL = 10 kΩ is connected to VDD/2
and VDD = 5.0V. Refer to Figure 2-13 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.
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 4-2) improves the
feedback loop’s stability by making the output load
resistive at higher frequencies; the bandwidth will
usually be decreased.

Bench measurements are helpful in choosing RISO.
Adjust RISO so that a small signal step response (see
Figure 2-14) has reasonable overshoot (e.g., 4%).

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 other nearby analog parts.
4.5
Unused Op Amps
FIGURE 4-4:
Layout.
1.
An unused op amp in a quad package (e.g., MCP6L04)
should be configured as shown in Figure 4-3. 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; 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
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; this is greater than this
family’s bias current at +25°C (1 pA, typical).
Example Guard Ring
Inverting Amplifiers (Figure 4-4) 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’s input (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 guard ring to the inverting input
pin (VIN–); this biases the guard ring to the
common mode input voltage.
b) Connect the non-inverting pin (VIN+) to the
input with a wire that does not touch the
PCB surface.

ACTIVE LOW-PASS FILTER
The MCP6L01/1R/1U/2/4 op amp’s low input bias
current makes it possible for the designer to use larger
resistors and smaller capacitors for active low-pass
filter applications. However, as the resistance
increases, the noise generated also increases. Parasitic capacitances and the large value resistors could
also modify the frequency response. These trade-offs
need to be considered when selecting circuit elements.
Figure 4-5 shows a second-order Bessel filter with
100 Hz cutoff frequency and a gain of +1 V/V. The
component values were selected using Microchip’s
FilterLab® software; the capacitor values were reduced
to a more common range.
C1
100 pF
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.
Figure 4-4 shows an example of this type of layout..

DESIGN AIDS
Microchip provides the basic design aids needed for
the MCP6L01/1R/1U/2/4 family of op amps.
5.1
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.

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.
•
