Operational transconductance amplifier for converting control voltage to current (V->A).


The heart of the circuit is the differential amplifier made up of resistors R1, R2 and the transistors Q1, Q2. The amount of voltage is mirrored on the output in current. 0-5V gives 0-8A. May be used for controlling synthesiser circuits such as filter or oscillator.
