General Description
The Microchip Technology Inc. MCP6V61/1U/2/4
family of operational amplifiers provides input offset
voltage correction for very low offset and offset drift.
These devices have a gain bandwidth product of
1 MHz (typical). They are unity-gain stable, have
virtually no 1/f noise and have good Power Supply
Rejection Ratio (PSRR) and Common Mode Rejection
Ratio (CMRR). These products operate with a single
supply voltage as low as 1.8V, while drawing
80 µA/amplifier (typical) of quiescent current.
The Microchip Technology Inc. MCP6V61/1U/2/4 op
amps are offered in single (MCP6V61 and
MCP6V61U), dual (MCP6V62) and quad (MCP6V64)
packages. They were designed using an advanced
CMOS process.

FIGURE 2:
Input Offset Voltage vs.
Ambient Temperature with VDD = 5.5V.
As seen in Figures 1 and 2, the MCP6V61/1U/2/4 op
amps have excellent performance across temperature.
The input offset voltage temperature drift (TC1) shown
is well within the specified maximum values of
15 nV/°C at VDD = 5.5V and 30 nV/°C at VDD = 1.8V.
This performance supports applications with stringent
DC precision requirements. In many cases, it will not be
necessary to correct for temperature effects (i.e.,
calibrate) in a design. In the other cases, the correction
will be small.
