AD421BNZ

Overview

The AD421BNZ is a complete, loop-powered digital-to-analog converter (DAC) designed for industrial control applications. It converts digital inputs into a 4 mA to 20 mA current output suitable for standard process loops. The device features 16-bit resolution with guaranteed monotonicity and an integral nonlinearity of ±0.01% FSR. It integrates a 5 V or 3 V regulator output, precision voltage references (2.5 V and 1.25 V), and supports HART® communication protocols. Powered by a single supply between 2.95 V and 5.05 V, it operates within a temperature range of -40°C to +85°C in a 16-lead SOIC package.

Feature Summary

16-bit resolution with 0.01% INL and monotonic performance
Integrated 4 mA to 20 mA current output driver
HART® protocol compatible for smart transmitter applications
Built-in 2.5 V and 1.25 V precision voltage references

Applications

Loop-powered smart transmitters in industrial control systems
Process automation instrumentation requiring 4-20 mA signaling
High-precision analog output stages in hazardous environments

Part Context

The AD421BNZ belongs to the AD421 family of loop-powered DACs from Analog Devices. The 'B' suffix indicates a commercial/industrial temperature grade (-40°C to +85°C), while 'N' denotes the 16-lead SOIC package. This component serves as a compact, fully integrated solution for replacing discrete designs in traditional 4-20 mA loop-powered devices.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the AD421BRZ (SOIC package, wider temp range) and AD421ARZ (wide temp range). For legacy through-hole requirements, the AD421BN (non-Z suffix) may be considered if RoHS compliance is not mandatory. Verify interface timing and reference configuration compatibility when substituting.
