LIA120

Optically Isolated Linear Error Amplifier

Features

Description

• Optocoupler, precision reference and error

amplifier in single package

• Low voltage operation 2.7V

• 1.240V ± 2.5% reference

• CTR Matching 15%

• >70dB THD

• 70dB CMRR

• 3,750V_rmsisolation

• UL approval pending

The LIA120 Optically Isolated Reference Amplifier

combines Clare’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.

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.

Applications

• Power supply feedback

• Telecom central office supply

•

Telecom bricks

• Modem transformer replacement

• Digital telephone isolation

By using the LIA120, system designers can save

precious board space and reduce component count.

Available in an 8 pin surface mount package.
