Microchip MCP3564R ADC

2/4/8-Channel, 153.6 kSPS, Low-Noise 24-bit Delta-Sigma

The Microchip MCP3564R ADC is fully configurable with Oversampling Ratio (OSR) from 32 to 98304 and gain from 0.33X to 64X. It includes an internal sequencer(SCAN mode) with multiple monitor channels and a 24-bit timer to be able to automatically create conversion loop sequences without needing MCU communications. Advanced security features such as CRC and register map lock, can guarantee configuration locking and integrity as well as communication data integrity for secure environments.

The ADC also features a 20 MHz SPI-compatible serial interface. Communication is largely simplified with 8-bit commands, including various continuous Read/Write modes and 24/32-bit multiple data formats that can be accessed by the Direct Memory Access (DMA) of an 8-bit, 16-bit or 32-bit MCU. The MCP3564R is available in an ultra-small, 3 mm x 3 mm UQFN-20, and leaded 6.4 mm x 6.4mm TSSOP-20 package and is specified over an extended temperature range from -40°C to +125°C.

The MCP3561R is a similar device with just one differential (two single ended) input channel(s), but equivalent performance and functionality.

The MCP3562R is a similar device with just two differential (four single ended) input channels, but equivalent performance and functionality.
