The MCP3561/2/4 and the MCP3461/2/4 are 24-bit/16-bit low-noise Delta-Sigma Analog-to-Digital Converters (ADCs), with 2/4/8 single-ended or 1/2/4 differential input channels and programmable data rate of up to 153.6 kSPS. These devices are fully configurable with Oversampling Ratio (OSR) from 32 to 98304 and gain from 1/3X to 64X. Integrated features such as internal oscillator, temperature sensor and burnout sensor detection. These devices offer internal sequencer (SCAN mode) with multiple monitor channels and a 24-bit timer. And they come with a 20 MHz SPI-compatible serial interface. Communication is largely simplified with 8-bit commands.
