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.
Six Synchronous Sampling 16/24-bit Resolution Delta-Sigma A/D Converters with Proprietary Multi-Bit Architecture
91 dB SINAD, -100 dBc Total Harmonic Distortion (THD) (up to 35th harmonic), 102 dB Spurious-free Dynamic Range (SFDR) for Each Channel
Programmable Data Rate up to 64 ksps
Ultra-Low-Power Shutdown Mode with <2 μA
-115 dB Crosstalk Between any Two Channels
Low Drift Internal Voltage Reference: 5 ppm/°C
Differential Voltage Reference Input Pins
High Gain PGA on Each Channel (up to 32 V/V)
Phase Delay Compensation Between Each Pair of Channels with 1 μs Time Resolution
