Description
●The LM134/LM234/LM334 are 3-terminal adjustable current sources characterized by:
●■ an operating current range of 10000: 1
●■ an excellent current regulation
●■ 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.
●Features
●■ Operates from 1V to 40V
●■ 0.02%/V current regulation
●■ Programmable from 1µA to 10mA
●■ ±3% initial accuracy
