Linear Error Amplifier
Description
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.
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.
By using the LIA120, system designers can save
precious board space and reduce component count.
Available in an 8-pin surface mount package.
