Description: 3-Terminal Adjustable Current Sources

Features

* 1
* 2 Operates From 1V to 40V
* 0.02%/V Current Regulation
* Programmable From 1μA to 10mA
* True 2-Terminal Operation
* Available as Fully Specified Temperature Sensor

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 add
