1B22AN Description

Short technical summary and product information.

The 1B22AN is a programmable, isolated voltage-to-current (V/I) converter from Analog Devices. It incorporates transformer isolation to achieve high performance and reliability, making it suitable for industrial applications with high common-mode interference.

 

The device offers pin-programmable input voltage ranges of 0 to 5 V or 0 to 10 V, and output current ranges of 4 to 20 mA or 0 to 20 mA. It provides 1500 V RMS galvanic isolation between input and output, with low nonlinearity of ±0.05% max (typical 0.02%), low offset drift of 300 nA/°C, and low gain drift of 50 ppm/°C. Common mode rejection is 90 dB minimum.

 

An internal isolated loop supply drives up to 1000 Ω load. The device includes normal-mode output protection up to 240 V RMS and meets IEEE STD 472 for common-mode transient protection. It is available in a 12-DIP through-hole package and operates over -40°C to 85°C.

 

Typical applications include multichannel process control, D/A converter to current loop interfaces, analog transmitters and controllers, and remote data acquisition systems. The compact 1.0" x 2.10" x 0.35" plastic package facilitates integration.
