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 channels 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 singlesupply 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.
