LM334S8#PBF

LM334 is a three-terminal current source designed to operate at current levels from 1µA to 10mA, as set by an external resistor. This device operates as a true two terminal current source, requiring no extra power connections or input signals. Regulation is typically 0.02%/V and terminal-to-terminal voltage can range from 800mV to 40V. Because the operating current is directly proportional to absolute temperature in degrees Kelvin, this device will also find wide applications as a temperature sensor. The temperature dependence of the operating current is 0.336%/°C at room temperature. For example, a device operating at 298µA will have a temperature coefficient of 1µA/°C. It is used in application such as current mode, temperature sensing, constant current source for shunt references, cold junction compensation, constant-gain bias for bipolar differential stage, micropower bias networks, buffer for photoconductive cell, current limiter etc.
