AD420AN

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. The AD420 can alternatively provide a voltage output
from a separate pin that can be configured to provide 0 V to 5 V,
0 V to 10 V, ?5 V, or ?10 V with the addition of a single external
buffer amplifier
