The MCP3561RT-E/NC with Analog to Digital Converters - ADC 24-bit delta-sigma ADC wVref Single channel 3V is an integrated circuit manufactured by Microchip. It is a 24-bit delta-sigma ADC with a single-ended analog input voltage range of 0 mV to 3 V. It features an 8-bit I2C serial interface allowing for single-byte read and write operations. This device is ideal for use in applications requiring a small form factor and high resolution analog-to-digital conversion. The MCP3561RT-E/NC offers an over-temperature protection with auto-reset, a software controllable power-down mode, and an on-chip reference voltage source. It provides a high sampling rate of 148 kSps (kHz samples per second) and is designed for low-voltage operation, down to 1.8 V.
