MCP3903 Description

The MCP3903 is a six-channel Analog Front End (AFE) containing three pairs made out of two synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC) with PGA, a phase delay pensation block, internal voltage reference, and high-speed 10 MHz SPI patible serial interface. The converters contain a proprietary dithering algorithm for reduced idle tones and improved THD. The internal register map contains 24-bit...
