LM234D datasheet



The LM134, LM234, LM334 are 3-terminal adjustable current sources characterized by :

1. an operating current range of 10000: 1

2. an excellent current regulation

3. a wide dynamic voltage range of 1V t 10V

The current is determined by an external resistor without requiring other external components.
Reverse voltages of up to 20V will only draw a current of several microamperes. This enables the
circuit to operate as a rectifier and as a source of  current in a.c. applications.


1. Operates from 1V to 40V

2. 0.02%/V current regulation

3. Programmable from 1μA to 10mA

4. ±3% initial accuracy
