Analog isolation amplifier circuit | Forum Hi there, I am new to this forum and I am looking for some suggestions. In my application I have some isolated hall effect current and voltage sensors, each giving an output current (IM) up to 50mA (e.g. LEM LAX 100 NP).This current then goes to a resistor (R1) and gets converted into a 10V signal, which is then measured by another circuit (not displayed below). Index 6 Sensor Circuit Circuit Diagram SeekIC The circuit shown in the picture is a precise optical control circuit, and its work is noteffected by supply voltage and ambient temperature. Resistors R1, R2, R6 andphotosensitive resistor R5 form thetwo bridge of Wheatstone bridge together.
