Description
The Microchip Technology Inc. MCP6V26/7/8 family of
operational amplifiers provides input offset voltage
correction for very low offset and offset drift. These
devices have a wide gain bandwidth product (2 MHz,
typical) and strongly reject switching noise. 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 2.3V, while
drawing 620 µA/amplifier (typical) of quiescent current.
The Microchip Technology Inc. MCP6V26/7/8 op amps
are offered as a single (MCP6V26), single with Chip
Select (CS) (MCP6V28) and dual (MCP6V27). They
were designed using an advanced CMOS process.
