DESCRIPTION
The Microchip Technology Inc. MCP601/602/603/604
family of low power operational amplifiers are offered in
single (MCP601), single with a Chip Select pin feature
(MCP603), dual (MCP602) and quad (MCP604) configurations. These operational amplifiers (op amps) utilize
an advanced CMOS technology, which provides low
bias current, high speed operation, high open-loop gain
and rail-to-rail output swing. This product offering operates with a single supply voltage that can be as low as
2.7V, while drawing less than 325µA of quiescent current. In addition, the common-mode input voltage
range goes 0.3V below ground, making these amplifiers ideal for single supply operation.
These devices are appropriate for low-power battery
operated circuits due to the low quiescent current, for
A/D Converter driver amplifiers because of their wide
bandwidth, or for anti-aliasing filters by virtue of their
low input bias current.

The MCP601, MCP602 and MCP603 are available in
standard 8-lead PDIP, SOIC and TSSOP packages.
The quad MCP604 is offered in 14-lead PDIP, SOIC
and TSSOP packages. PDIP and SOIC packages are
fully specified from -40°C to +85°C with power supplies
from 2.7V to 5.5V.
