Device Overview

Summary

The MCP3912 is a 3V four channel Analog-Front-End (AFE) containing four synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC), four PGAs, phase delay compensation block, internal voltage reference, digital offset and gain error calibration registers and high-speed 20 MHz SPI compatible serial interface.  The MCP3912 AFE is capable of interfacing to a variety of voltage and current sensors including shunts, current transformers, Rogowski coils and Hall effect sensors

MCP3912 Evaluation Board
MCP3912 Evaluation Board ( ADM00499 )

The MCP3912 ADC Evaluation Board system provides the opportunity to evaluate the performance of the MCP3912 four-channel Analog Front End (AFE). It also provides a development platform for 16-bit microcontroller-based applications, using the existing 100-pin PIC ® microcontroller Plug-in Module (PIM) systems that are compatible with Explorer 16 Evaluation Board (DM240001) and other high pin...
