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.
