Product Overview

The LM334DT is a 3-terminal adjustable Current Source characterized by an operating current range of 10000: 1 an excellent current regulation wide dynamic voltage range of 1 to 10V. The current is determined by an external resistor without requiring other external components. Reverse voltage 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 AC applications. For the 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.
  • Operates from 1 to 40V
  • Programmable from 1µA to 10mA
  • 0.02%/V current regulation
  • ±3% Initial accuracy
