查看全系列相关产品产品概述
The MCP3911A0-E/SS is a 2-channel Analog Front End (AFE) containing two synchronous sampling delta-sigma analog-to-digital converters (ADC), two PGAs, phase delay compensation block, low-drift internal voltage reference, modulator output block, digital offset and gain errors calibration registers and high-speed 20MHz SPI compatible serial interface. The MCP3911 ADCs are fully configurable with features such as, 16/24-bit resolution, OSR from 32 to 4096, gain from 1x to 32x, independent shutdown and reset, dithering and auto-zeroing. The MCP3911 is capable of interfacing a large variety of voltage and current sensors including shunts, current transformers, Rogowski coils and Hall effect sensors.
