In stock at distributor Digi-Key is Microchip Technology's MCP3565R low-noise 24-bit delta-sigma analogue-to-digital converter (ADC) with two single-ended or one differential input channels and a programmable data rate of up to 153.6 kSPS.

It offers integrated features such as internal VREF, oscillator, temperature sensor, and burnout sensor detection to reduce system component count and total solution cost.

The MCP3565R 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 several monitor channels and a 24-bit timer for creating conversion loop sequences automatically without needing MCU communications.

Advanced security features, such as CRC and register map lock, can assure configuration locking and integrity as well as communication data integrity for secure environments.

The device 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 MCP3565R is available in an ultra-small, 2 mm x 2 mm UQFN-12 and is specified over an extended temperature range from -40°C to +125°C.
