Описание

The MCP3903-I/SS is a 6-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 compensation block, internal voltage reference and high-speed 10MHz SPI compatible serial interface. The converters contain a proprietary dithering algorithm for reduced idle tones and improved THD. The internal register map contains 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. The MCP3903 is capable of interfacing to a large variety of voltage and current sensors including shunts, current transformers, Rogowski coils and hall-effect sensors.

• 91dB SINAD, -100dBc Total harmonic distortion (THD) (up to 35th harmonic)
• 109dB Spurious-free dynamic range (SFDR) for each channel
• Programmable data rate up to 64ksps
• Ultra low-power shutdown mode with <2µA
• -115dB Crosstalk between the two channels
• 5ppm/°C Low drift internal voltage reference
• Differential voltage reference input pins
• High gain PGA on each channel (up to 32V/V)
• Phase delay compensation between the two channels with 1µs time resolution
• Separate modulator outputs for each channel
• High-speed, addressable 20MHz SPI Interface with Mode 0.0 and 1.1 compatibility
