LM234 - 3-Terminal Adjustable Current Sources

Download the LM234 datasheet PDF. This datasheet also covers the LM234H variant, as both devices belong to the same 3-terminal adjustable current sources family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM134/LM234/LM334 are 3-terminal adjustable current sources featuring 10,000:1 range in operating current, excellent current regulation and a wide dynamic voltage range of 1V to 40V.

Current is established with one external resistor and no other parts are required.

LM134/LM234/LM334 3-Terminal Adjustable Current Sources March 2000 LM134/LM234/LM334 3-Terminal Adjustable Current Sources General Description The LM134/LM234/LM334 are 3-terminal adjustable current sources featuring 10,000:1 range in operating current, excellent current regulation and a wide dynamic voltage range of 1V to 40V. Current is established with one external resistor and no other parts are required. Initial current accuracy is ±3%. The LM134/LM234/LM334 are true floating current sources with no separate power supply connections. In addition, reverse applied voltages of up to 20V will draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications.
