AD420ARZ-32 Description

Short technical summary and product information.

The AD420ARZ-32 is a complete, single-chip digital-to-current loop output converter designed for industrial control applications. It provides 16-bit resolution with ±0.012% maximum integral nonlinearity (INL) and ±0.05% maximum offset error (trimmable), ensuring high accuracy in current loop signal generation.

 

This device supports programmable output current ranges: 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA, selectable via range select pins. It also features an optional buffered voltage output. The serial digital interface operates at up to 3.3 Mbps, compatible with SPI protocols. An on-chip 5 V reference (25 ppm/°C maximum drift) simplifies system design, while an asynchronous CLEAR function resets the output to zero scale.

 

The AD420ARZ-32 includes comprehensive fault detection for open loop conditions, enhancing system reliability. It operates from a single power supply of 12 V to 32 V with an output loop compliance of 0 V to VCC − 2.75 V. The device is available in a compact 24-lead SOIC (surface mount) package and operates over the industrial temperature range of -40°C to 85°C. Its sigma-delta architecture ensures low noise and excellent linearity.
