LM334
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 to 40V The current is determined by an external resistor without requiring other external ponents. 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. For the LM134/LM234/LM334, the voltage on the control pin is 64m V at +25o C and is directly proportionalto the absolute temperature (o K). The simplest external resistor connection generates a current with ≈ 0.33%/o C temperature dependence. Zero drift can be obtainedby adding an additionalresistor and a diode to the external circuit.
