The AD421BRZRL is a 16-bit, loop-powered digital-to-analog converter (DAC) from Analog Devices Inc. designed for 4-20 mA current loop applications in smart industrial transmitters. It provides a single-chip solution with high accuracy and low power consumption.
Key specifications include 16-bit resolution and monotonicity, 0.01% typical integral nonlinearity (INL), and an 8 ms typical settling time to ±0.1% full scale. The device features a pin-selectable regulator output (3V, 3.3V, or 5V) and precision internal references (1.25V and 2.5V). It draws a maximum quiescent current of 750 µA and is fully compatible with HART FSK protocol.
Housed in a 16-lead SOIC surface mount package (0.295" width, 7.50mm body), the AD421BRZRL operates over a temperature range of -40°C to 85°C. The loop-powered architecture allows the DAC to be powered entirely from the current loop, simplifying system design.
