Description
The Microchip Technology Inc. MCP6V27 dual
operational amplifier has input offset voltage correction
for very low offset and offset drift. This device has a
wide gain bandwidth product (2 MHz, typical) and
strongly rejects switching noise. It is unity gain stable,
has no 1/f noise, and has good PSRR and CMRR. This
product operates with a single supply voltage as low as
2.3V, while drawing 620 µA/amplifier (typical) of
quiescent current.
The Microchip Technology Inc. MCP6V27 op amp is
offered as a dual. It is designed in an advanced CMOS
process.
