The MCP3561/2/4/R are low-noise 24-bit Delta-Sigma Analog-to-Digital Converter (ADC), with two single-ended or one differential input channels and programmable data rate of up to 153.6 kSPS. It offers integrated features such as oscillator, internal voltage reference, temperature sensor and burnout sensor detection, to reduce components and cost.
The devices also feature 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.
