MCP6S21/2/6/8
Description
The Microchip Technology Inc. MCP6S21/2/6/8 are
analog Programmable Gain Amplifiers (PGA). They
can be configured for gains from +1 V/V to +32 V/V and
the input multiplexer can select one of up to eight chan-
nels through an 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 MCP6S21 and the two channel
MCP6S22 are available in 8-pin PDIP, SOIC and
MSOP packages. The six channel MCP6S26 is avail-
able in 14-pin PDIP, SOIC and TSSOP packages. The
eight channel MCP6S28 is available in 16-pin PDIP
and SOIC packages. All parts are fully specified from
-40°C to +85°C.
