Description:

3-Terminal Adjustable Current Sources

Features

* n n n n n n 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 ± 3% initial accuracy Connection Diagrams SO-8 Surface Mount Package SO-8 Alternative Pinout Surface Mount Package TO-46 Metal Can

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 addi
