LM134-LM234-LM334
Three terminal adjustable current sources
Features
■ Operates from 1V to 40V
■ 0.02%/V current regulation
■ Programmable from 1µA to 10mA
■ ±3% initial accuracy
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.
For the LM134/LM234/LM334, the voltage on the
control pin is 64mV at +25°C and is directly
proportional to the absolute temperature (°K). The
simplest external resistor connection generates a
current with approximately 0.33%/°C temperature
dependence. Zero drift can be obtained by adding
an additional resistor and a diode to the external
circuit.
