Description
The MCP3901 is a dual channel Analog Front End
(AFE) containing two synchronous sampling Delta-
Sigma Analog-to-Digital Converters (ADC), two PGAs,
phase delay compensation block internal voltage
reference, modulator output block, and high-speed
20 MHz SPI compatible serial interface. The converters
contain a proprietary dithering algorithm for reduced
Idle tones and improved THD.
The internal register map contains 24-bit wide ADC
data words, a modulator output byte, as well as six
writable
control
registers

dithering,
shutdown, Reset and several communication features.
The communication is largely simplified with various
Continuous Read modes that can be accessed by the
Direct Memory Access (DMA) of an MCU and with a
separate data ready pin that can be connected directly
to an Interrupt Request (IRQ) input of an MCU.
The MCP3901 is capable of interfacing to a large
variety of voltage and current sensors, including
shunts, current transformers, Rogowski coils and Hall-
effect sensors.
