24 Bit 0.635 mm AFE -- Series MCP3903 28-SSOP (0.209, 5.30mm Width)
MCP3903-E/SS Description
The MCP3903-E/SS is a six-channel Analog Front End (AFE) containing three pairs made out of two synchronous samplings Delta-Sigma Analog-to-Digital
Converters (ADC) with PGA, a phase delay compensation block, internal voltage reference, and high-speed 10 MHz SPI compatible serial interface.
The converters contain a proprietary dithering algorithm for reduced idle tones and improved THD. The internal register map contains a 24-bit wide
ADC data words, a modulator output register as well as six 24-bit writable control registers to program gain, over-sampling ratio, phase, resolution, dithering,
shut down, reset, and several communication features.
