The LM334MX/NOPB 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 1 to 40V. Current is established with one external resistor and no other parts are required. Initial current accuracy is ±3%. The LM334 is 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. The sense voltage used to establish operating current in the LM134 is 64mV at 25°C and is directly proportional to absolute temperature (°K). The simplest one external resistor connection, then, generates a current with ≈+0.33%/°C temperature dependence. Zero drift operation can be obtained by adding one extra resistor and a diode.

• 0.02%/V current regulation
• Programmable from 1μA to 10mA
• True 2-terminal operation
• Available as fully specified temperature sensor
