Description
The MCP616/7/8/9 family of operational amplifiers (op
amps) from Microchip Technology Inc. are capable of
precision, low-power, single-supply operation. These
op amps are unity-gain stable, have low input offset
voltage (±150 µV, maximum), rail-to-rail output swing
and low input offset current (0.3 nA, typical). These
features make this family of op amps well suited for
battery-powered applications.
The single MCP616, the single MCP618 with Chip
Select (CS) and the dual MCP617 are all available in
standard 8-lead PDIP, SOIC and MSOP packages. The
quad MCP619 is offered in standard 14-lead PDIP,
SOIC and TSSOP packages. All devices are fully
specified from -40°C to +85°C, with power supplies
from 2.3V to 5.5V.
