LM13600 Dual Operational Transconductance Amplifiers with Linearizing Diodes and Buffers
The LM13600 series consists of two current controlled transconductance amplifiers each with differential inputs and push-pull 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. The result is a 10 dB signal-to-noise improvement referenced to 0.5 percent THD. Controlled impedance buffers which are especially designed to complement the dynamic range of the amplifiers are provided.
