Features

Description

• Optocoupler, precision reference and error amplifier

in single package

• Low voltage operation 2.7V

• 1.240V 2.ꢀ5 reference

• CTR Matching 1ꢀ5

• >70dB THD

• 70dB CMRR

• 3,7ꢀ0V_rmsisolation

• UL approval pending

The LIA120 Optically Isolated Reference Amplifier

combines IXYS IC Division’s linear optical coupler

technology with an industry standard 431 type

precision programmable shunt regulator to provide

very linear high gain with excellent temperature

stability for a total gain error of less than 2dB. By using

optical feedback, the LIA120 essentially eliminates

temperature and gain variations due to current

transfer ratio (CTR) changes in optocouplers while

increasing the bandwidth up to 10X and easing

engineering design constraints.

Applications

• Power supply feedback

• Telecom central office supply

• Telecom bricks

• Modem transformer replacement

• Digital telephone isolation

The LIA120 is very well suited for high gain feedback

amplifiers that require excellent linearity and low

temperature variation such as isolated power

supply feedback stages, modem audio transformer

replacement, isolated industrial control signals, and

sensor feedback.

Block Diagram

By using the LIA120, system designers can save

precious board space and reduce component count.

Available in an 8 pin surface mount package.
