アナログ・デジタルコンバータ - ADC 3 Chnl Energy Meter Front End 3V SPI/2 AFE General Purpose 3ADC 24Bit 3.3V Automotive Medical 28Pin SSOP T/R
The MCP3919A1-E/SS is a 3-channel Analog Front End (AFE) containing three synchronous sampling delta-sigma analog-to-digital converters (ADC), three PGAs, phase delay compensation block, low-drift internal voltage reference, digital offset and gain error calibration registers and high-speed 20MHz SPI-compatible serial interface. The MCP3919 ADCs are fully configurable with features such as: 16/24-bit resolution, Oversampling Ratio (OSR) from 32 to 4096, gain from 1x to 32x, independent Shutdown and Reset, dithering and autozeroing. The MCP3919 includes advanced security features to secure the communications and the configuration settings such as a CRC-16 checksum on both serial data outputs and static register map configuration. The MCP3919 is capable of interfacing with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and hall-effect sensors.
