DESCRIPTION
The LM134/LM234/LM334 are 3-terminal adjust-
able current sources characterized by:
u an operating current range of 10000: 1
u an excellent current regulation
u 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 cur-
rent 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 pro-
portional to the absolute temperature (°K). The
simplest external resistor connection generates a
current with
≈ 0.33%/°C temperature dependence.
Zero drift can be obtained by adding an additional
resistor and a diode to the external circuit.
