Manufacturer:Legerity Description:The LE57D111TC/LE57D111TC234/LE57D111TC are 3-terminal adjustable current sources featuring 10,000:1 range in operating current, excel- lent current regulation and a wide dynamic voltage range of 1V to 40V. Current is established with one external resistor and no other parts are required. Initial current accuracy is 3%. The LE57D111TC/LE57D111TC234/LE57D111TC are true floating current sources with no separate power supply connections. In addi- tion, 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. The sense voltage used to establish operating current in the LE57D111TC is 64mV at 25˚C and is directly proportional to abso- lute temperature (˚K). The simplest one external resistor connection, then, generates a current with +0.33%/˚C tem- perature dependence. Zero drift operation can be obtained by adding one extra resistor and a diode. Applications for the current sources include bias networks, surge protection, low power reference, ramp generation, |
