LIA136 Datasheet Error Amplifiers

Manufacturer: IXYS (now Littelfuse)

Overview: INTEGRATED CIRCUITS DIVISION LIA135 / LIA136 Low Voltage Optically Isolated Error.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LIA135 and LIA136 are low voltage optically isolated error amplifiers with a precision programmable shunt reference combined into a single package capable of operating down to 1.6V.

The optocoupler portion of the LIA135 / LIA136 comprises an infrared LED that is optically coupled to an NPN phototransistor providing a current transfer ratio from 500% to 2000%.

Ensuring low voltage performance, the input voltage range of 1.6V to 10V is guaranteed over the operational temperature range.
