AD421BRZRL Description

Short technical summary and product information.

The AD421BRZRL is a high-performance, low-cost single-chip solution for generating 4 mA to 20 mA signals, specifically designed for smart industrial control transmitters. It offers 16-bit resolution and monotonicity, with an integral nonlinearity of 0.01% maximum.

This DAC includes a selectable regulator output, providing +3 V, +3.3 V, or +5 V, which can power additional circuits within the transmitter. It also features on-chip precision references of +1.25 V and +2.5 V, eliminating the need for external components.

The AD421BRZRL is fully compatible with standard HART circuitry and similar FSK protocols. It converts digital data to current with a full-scale settling time typically occurring within 8 ms to ±0.1%. The device also includes a programmable alarm current capability for transducer fault indication.

Packaged in a 16-lead SOIC, the AD421BRZRL is loop-powered and suitable for industrial control applications requiring precise current output.
