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) config-
urations. 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 oper-
ates with a single supply voltage that can be as low as
2.7V, while drawing less than 325
μ
A of quiescent cur-
rent. In addition, the common-mode input voltage
range goes 0.3V below ground, making these amplifi-
ers 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 MCP601 is also available in the SOT23-5 pack-
age. The quad MCP604 is offered in 14-lead PDIP,
SOIC and TSSOP packages. PDIP and SOIC pack-
ages are fully specified from -40
°
C to +85
°
C with power
supplies from 2.7V to 5.5V.
