Description
The Microchip Technology Inc. MCP6V06/7/8 family of
operational amplifiers has input offset voltage
correction for very low offset and offset drift. These
devices have a wide gain bandwidth product (1.3 MHz,
typical) and strongly reject switching noise. They are
unity gain stable, have no 1/f noise, and have good
PSRR and CMRR. These products operate with a
single supply voltage as low as 1.8V, while drawing
300 µA/amplifier (typical) of quiescent current.
The Microchip Technology Inc. MCP6V06/7/8 op amps
are offered in single (MCP6V06), single with Chip
Select (CS) (MCP6V08), and dual (MCP6V07). They
are designed in an advanced CMOS process.
