The transconductance amplifier differs from the standard op-amp in two ways:
The output is a constant current source whose output is proportional to the input voltage.
The gain,or more correctly,the transconductance,is set externally by the adjustment of the current through the bias terminal.This controls the magnitude of the constant current source.
These unique features offer accurate gain without the use of negative feedback.This eliminates closed loop phase shift that can cause oscillations in conventional amplifiers.
The surface mount NJM13600 consists of two voltage controlled current (transconductance) amplifiers each with differential inputs and a push pull output.
The two amplifiers share common supplies but otherwise operate independently.
Linearising diodes are provided at the inputs to reduce distortion and allow higher input levels.The result is a 10dB signal to noise improvement referenced to 0.5% THD.
Controlled impedance buffers are provided which are designed to complement the dynamic range of the amplifiers.
