MCP3911 Description
The MCP3911 is a 2.7V to 3.6V dual channel Analog Front End (AFE) containing two synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC), two PGAs, phase delay pensation block, low-drift internal voltage reference, modulator output block, digital offset and gain errors calibration registers and high-speed 20 MHz SPI patible serial interface. The MCP3911 ADCs are fully configurable.
