概要

Description

The AD5421BREZ is a 16-bit, current-output DAC (Digital-to-Analog Converter) from Analog Devices, designed for industrial control applications. It provides a 4–20 mA or 0–20 mA output with high accuracy (±0.01% FSR) and low drift.
Key features:
- 16-bit resolution for precise analog output.
- On-chip voltage reference (5 V, 10 ppm/°C).
- SPI-compatible serial interface for easy microcontroller integration.
- Programmable output ranges (4–20 mA, 0–20 mA, or 0–24 mA).
- HART®-compatible for industrial communication.
- Wide supply range (10.8 V to 40 V).
Applications include process control, PLCs, and smart transmitters. The AD5421BREZ comes in a 24-lead TSSOP package and operates over –40°C to +105°C, making it suitable for harsh environments.
For more details, refer to the datasheet on Analog Devices' website.
