MCP6S91/2/3
Description
The Microchip Technology Inc. MCP6S91/2/3 are
analog Programmable Gain Amplifiers (PGAs). They
can be configured for gains from +1 V/V to +32 V/V and
the input multiplexer can select one of up to two chan-
nels through a SPI port. The serial interface can also
put the PGA into shutdown to conserve power. These
PGAs are optimized for high-speed, low offset voltage
and single-supply operation with rail-to-rail input and
output capability. These specifications support single-
supply applications needing flexible performance or
multiple inputs.
The one-channel MCP6S91 and the two-channel
MCP6S92 are available in 8-pin PDIP, SOIC and MSOP
packages. The two-channel MCP6S93 is available in a
10-pin MSOP package. All parts are fully specified from
-40°C to +125°C.
