AD74115BCPZ-RL7

ADCs/DACs - Special Purpose Overview

The AD74115BCPZ-RL7 is a single-channel, software-configurable input and output device from Analog Devices Inc., housed in a 48-lead LFCSP package. It integrates a 16-bit sigma-delta ADC with optional 50 Hz and 60 Hz rejection, and a 14-bit monotonic DAC. The device supports voltage and current inputs/outputs, digital I/O, RTD measurements (2-wire, 3-wire, 4-wire), and thermocouple sensing. It operates on a wide power supply range of AVDD +6 V to +28.8 V and AVSS −2.5 V to −18 V, with DVCC between 2.7 V and 5.5 V. Communication is handled via an SPI interface, and it includes internal diagnostics such as open-circuit and short-circuit detection.
