AD421BRZRL Integrated Circuit Chip Loop-Powered 4mA To 20 mA Digital To Analog Converters

AD421BRZRL Integrated Circuit Chip Loop-Powered 4mA To 20 mA Digital To Analog Converters

Product Description Of AD421BRZRL
AD421BRZRL is a complete, loop-powered, digital to 4-20 mA converter, designed to meet the needs of smart transmitter manufacturers in the Industrial Control industry. It provides a high precision, fully integrated, low cost solution in a compact 16-pin package. The AD421BRZRL is ideal for extending the resolution of smart 4-20 mA transmitters at very low cost.

AD421BRZRL includes a selectable regulator that is used to power itself and other devices in the transmitter. This regulator provides either a +5 V, +3.3 V or +3 V regulated output voltage. The part also contains +1.25 V and +2.5 V precision references. The AD421BRZRL thus eliminates the need for a discrete regulator and voltage reference. The only external components required are a number of passive components and a pass transistor to span large loop voltages.
