Product Introduction
The MCP3911 is a 2.7V to 3.6V dual channel Analog Front End (AFE) containing two synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC), two PGAs, phase delay compensation block, low-drift internal voltage reference, modulator output block, Digital Offset and Gain Error Calibration registers and high-speed 20 MHz SPI compatible serial interface.
The MCP3911 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 communication is largely simplified with the one-byte long commands, including various continuous Read/Write modes that can be accessed by the Direct Memory Access (DMA) of an MCU with a separate Data Ready pin that can be directly connected to an Interrupt Request (IRQ) input of an MCU.
The MCP3911 is capable of interfacing a large variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and Hall effect sensors.
