• Available in Single, Dual and Quad
The Microchip Technology Inc. MCP601/2/3/4 family of
low-power operational amplifiers (op amps) are offered
in single (MCP601), single with Chip Select (CS)
(MCP603), dual (MCP602) and quad (MCP604)
configurations. These op amps utilize an advanced
CMOS technology that 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 230 µA (typ.) of quiescent current per
amplifier. 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 convert 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 MCP601 and MCP601R are also available in a
standard 5-lead SOT-23 package, while the MCP603 is
available in a standard 6-lead SOT-23 package. The
MCP604 is offered in standard 14-lead PDIP, SOIC and
TSSOP packages.
