The NTE870 consists of two current controlled transconductance amplifiers each with differential inputs and a pushpull output. The two amplifiers share common supplies but otherwise operate independently. Linearizing diodes are provided at the inputs to reduce distortion and allow higher input levels resulting in a 10dB signaltonoise improvement referenced to 0.5 percent THD. Controlled impedance buffers are provided which are especially designed to complement the dynamic range of the amplifiers.
