AD74115BCPZ

ADCs/DACs - Special Purpose Overview

The AD74115BCPZ is a single-channel, software-configurable input and output device designed for industrial control applications. 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 multiple configurable modes on a single pin, including voltage and current inputs/outputs, digital I/O, RTD measurements (2-wire, 3-wire, 4-wire), and thermocouple measurement. It features an SPI-compatible interface, overvoltage tolerant pins, and an internal temperature sensor with ±5°C accuracy. Operating within a wide power supply range of +6 V to +28.8 V for AVDD and -2.5 V to -18 V for AVSS, it functions reliably from -40°C to +105°C in a 48-lead LFCSP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for the intended deployment region. Cross-reference the datasheet revision to ensure all electrical parameters align with the production batch being procured.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single channel must handle diverse industrial signals such as 4-20 mA loops, RTDs, and thermocouples. Ensure the system design accommodates the required headroom and footroom voltages relative to AVDD and AVSS supplies. Verify that the SPI interface speed and GPIO capabilities meet the data rate requirements for digital input and output operations.

ADCs/DACs - Special Purpose Part Context

The AD74115 belongs to Analog Devices' family of software-configurable input and output devices. It is often paired with companion products like the ADP1034 for power and data isolation with programmable power control. The BC suffix indicates a specific temperature grade and package variant within the broader AD74115 product line.

ADCs/DACs - Special Purpose Replacement Considerations

Consult the manufacturer's official cross-reference guide for verified substitute part numbers. Ensure any replacement maintains compatibility with the 48-lead LFCSP package and supports the same SPI communication protocol and voltage supply ranges.
