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 channels 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 available 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.
