MCP6V11/1U
Description
The Microchip Technology Inc. MCP6V11/1U 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
80 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 1.6V, while drawing 7.5 µA/amplifier (typical) of
quiescent current.
The Microchip Technology Inc. MCP6V11/1U op amps
are offered in single (MCP6V11 and MCP6V11U)
packages. They were designed using an advanced
CMOS process.
