Product Introduction
The MCP3913 is a 3V six-channel Analog Front End (AFE), containing six synchronous sampling DeltaSigma, Analog-to-Digital Converters (ADC), six PGAs, phase delay compensation block, low-drift internal voltage reference, Digital Offset and Gain Error Calibration registers and high-speed 20 MHz SPI-compatible serial interface.
The MCP3913 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 communication is largely simplified with 8-bit commands, including various continuous Read/Write modes and 16/24/32-bit data formats that can be accessed by the Direct Memory Access (DMA) of an 8, 16 or 32-bit MCU, and with the separate Data Ready pin that can directly be connected to an Interrupt Request (IRQ) input of an MCU.
The MCP3913 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 MCP3913 is capable of interfacing with a variety of voltage and current sensors, including shunts, Current Transformers, Rogowski coils and Hall effect sensors.
