资料介绍

　　　　The MCP3901 is a dual channelAnalogFront End （AFE） containing two synchronous sampling DeltaSigma Analog-to-Digital Converte rs（ADC）， two PGAs， phase delay compensation block internal voltage reference， modulatoroutput block， and high-speed 20 MHz 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 wideADC data words， a modulator output byte， as well as six writable control registers to programgain， oversampling ratio， phase， resolution， dithering， shutdown， Reset and several communication features. The communication is largelysimplified with various Continuous Read modes thatcanbe accessed by the Direct Memory Access （DMA） of anMCUand with a separate data readypin that can be connected directly to an Interrupt Request （IRQ） input of an MCU. The MCP3901 is capable of interfacing to a large variety of voltage and current sensors， including shunts， current transformers， Rogowski coils and Halleffect sensors.
