The LM134/LM234/LM334 are 3-terminal adjustable current sources featuring a 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. The 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.
