MCP3912

In Production

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

      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...
