IC SENSOR TEMP ADJ CUR MODE TO92
LM334Z is an adjustable current sources. This article mainly introduce its pinout, application, datasheet PDF and other detailed informations about STMicroelectronics LM334Z.
LM334Z
The LM334Z is 3-terminal adjustable current sources characterized by:
■ an operating current range of 10000
■ 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 LM334Z, 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.
