0.1%2,7 В ~ 3,6 В3 фаза

Overview

The MCP3914A1T-E/MVVAO is a 3V eight-channel Analog Front End(AFE, containing eight synchronous sampling delta-sigma ADCs, eight PGAs, phase delay compensation block, low-drift internal voltage reference, digital offset and gain errorcalibration registers, and high-speed 20 MHz SPI compatible serial interface.The MCP3914A1T-E/MVVAO 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 auto-zeroing.The MCP3914A1T-E/MVVAO 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. It also includes a register-map lock through an 8-bit secure key to stop unwanted write commands from processing.The MCP3914A1T-E/MVVAO is capable of interfacing with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and Hall-effect sensors.
