The AD421BR is a complete, loop-powered, digital to 4 mA to 20 mA converter, specifically engineered for smart industrial control transmitters. This high-performance DAC offers 16-bit resolution and monotonicity, ensuring precise signal generation.
Key features include a selectable regulator output of +3 V, +3.3 V, or +5 V, which can power both the DAC and other external circuits. Additionally, it provides on-chip precision reference voltages of +1.25 V and +2.5 V. The AD421BR is fully compatible with HART® circuitry and similar FSK protocols, making it suitable for a wide range of industrial communication systems.
Packaged in a 16-SOIC, surface mount form factor, the device operates across a broad temperature range of -40°C to 85°C. Its flexible high-speed serial interface and programmable alarm current capability further enhance its utility in demanding industrial environments.
