The LM334Z is a 3-terminal adjustable current source 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 LM334Z is a true floating current source 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. The LM334Z is guaranteed over a temperature range of 0°C to +70°C.
