Optically Isolated Error Amplifiers
Optically Isolated Linear Error Amplifiers combine Clare’s optical
technology with an industry standard 431-type precision
programmable shunt regulator to provide linear isolated feedback
for power supply designs. The LIA120 features matched
photodiodes for linear high-gain response exhibiting excellent
temperature stability for a total gain error of less than 2dB.
Features
• Optocoupler, precision reference, and error amplifier in
• Low voltage operation 2.7V
• 3750 V
• Fully Matched IC Linear Optocoupler-LIA120
• 70dB Linearity (typ.) LIA120
Operational temperature range of -40
