General Description

The AD420 is a complete digital to current loop output converter, designed to meet the needs of the industrial control market.

It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in a compact 24-lead SOIC or PDIP package.

The output current range can be programmed to 4 mA to 20 mA, 0 mA to 20 mA or to an overrange function of 0 mA to 24 mA.
