Description
The Microchip Technology Inc. MCP6V31/1U family of
operational amplifiers provides input offset voltage
correction for very low offset and offset drift. These are
low power devices, with a gain bandwidth product of
300 kHz (typical). They are unity gain stable, have 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 23 µA/amplifier (typical) of
quiescent current.
The Microchip Technology Inc. MCP6V31/1U op amps
are offered in single (MCP6V31 and MCP6V31U)
packages. They were designed using an advanced
CMOS process.

Note 1: These parameters were characterized using the circuit in Figure 1-6. In Figure 2-36 and Figure 2-37,
there is an IMD tone at DC, a residual tone at 100 Hz and other IMD tones and clock tones.
2: High gains behave differently; see Section 4.3.3, Offset at Power Up.
3: tODR includes some uncertainty due to clock edge timing.
