LIA130S

LIA130 Optically Isolated Error Amplifier Features • Optocoupler, Precision Reference, and Error Amplifier in a Single Package • 1.240V ± 1% Reference (@ 25ºC) • Linear Optical Coupler Technology with an Industry Standard 431-type • CTR 300% to 600% Linearity • 3750Vrms Isolation Description The LIA130 is an optically isolated amplifier with a 431-type precision programmable shunt reference combined in the same package. The optocoupler portion of the LIA130 comprises a Gallium Arsenide (GaAs) light-emitting diode (LED) optically coupled to a silicon phototransistor. The current transfer ratio of the device is between 300% and 600%. The combination of features in the LIA130 is optimal for use in isolated AC-to-DC power supplies and DC-to-DC converters. It replaces several discrete components, saves valuable circuit board space, and reduces complexity. The device is available in DIP and surface-mount packages.
