Description:

The MCP3913 is a 3V six-channel Analog Front End

(AFE), containing six synchronous sampling delta-

sigma, 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.

Applications:

• Polyphase Energy Meters

• Energy Metering and Power Measurement

• Automotive

• Portable Instrumentation

• Medical and Power Monitoring

• Audio/Voice Recognition
