Current is established with one external resistor and no other parts are required. Initial current accuracy is ±3%. The LM134\/LM234\/LM334 are true floating current sources with no separate power supply connections. In addition, reverse applied voltages of up to 20V will draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-DIgNdkRTLoqii1xzfeDluZlgg0g\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-VlbZdQBTxoUfvfx0mjolAJeognd\"\u003eThe sense voltage used to establish operating current in the LM134 is 64mV at 25°C and is directly proportional to absolute temperature (°K). The simplest one external resistor connection, then, generates a current with ≈+0.33%\/°C temperature dependence. Zero drift operation can be obtained by adding one extra resistor and a diode.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-ErH0dAyBMo4LbcxZxmZlkZzfgyc\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-AYcJd66LeoVjIWx0ft3lQ5X3gxe\"\u003eApplications for the current sources include bias networks, surge protection, low power reference, ramp generation, LED driver, and temperature sensing. The LM234-3 and LM234-6 are specified as true temperature sensors with ensured initial accuracy of ±3°C and ±6°C, respectively. These devices are ideal in remote sense applications because series resistance in long wire runs does not affect accuracy. In addition, only 2 wires are required.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-DvFOdNQrooi0P4x8OQ9laBHvg2c\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-Hy47dIX2doqJ3wxygtSlNRLegeh\"\u003eThe LM134 is specified over a temperature range of −55°C to +125°C, the LM234 from −25°C to +100°C and the LM334 from 0°C to +70°C.
