Description
The Microchip Technology Inc. MCP6051/2/4 family of
operational amplifiers (op amps) has low input offset
voltage (±150 µV, maximum) and rail-to-rail input and
output operation. This family is unity gain stable and
has a gain bandwidth product of 385 kHz (typical).
These devices operate with a single supply voltage as
low as 1.8V, while drawing low quiescent current per
amplifier (30 µA, typical). These features make the
family of op amps well suited for single-supply, high
precision, battery-powered applications.
The MCP6051/2/4 family is offered in single
(MCP6051), dual (MCP6052), and quad (MCP6054)
configurations.
The MCP6051/2/4 is designed with Microchip’s
advanced CMOS process. All devices are available in
the extended temperature range, with a power supply
range of 1.8V to 6.0V.

1.3 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.
EQUATION 1-1:
GDM = RF ⁄ RG
VCM = (VP + VDD ⁄ 2) ⁄ 2
VOST = VIN– – VIN+
VOUT = (VDD ⁄ 2) + (VP – VM) + VOST(1 + GDM)
Where:
GDM = Differential Mode Gain
VCM = Op Amp’s Common Mode
Input Voltage
VOST = Op Amp’s Total Input Offset
