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.主要特性
- Operates from 1V to 40V
- Programmable from 1µA to 10mA
- 0.02%/V current regulation
- ±3% initial accuracy
