Description
General Description
The LM13600 series consists of two current controlled
transconductance amplifiers each with differential inputs and
a push-pull output. The two amplifiers share common sup-
plies but otherwise operate independently. Linearizing di-
odes are provided at the inputs to reduce distortion and allow
higher input levels. The result is a 10 dB signal-to-noise im-
provement referenced to 0.5 percent THD. Controlled im-
pedance buffers which are especially designed to comple-
ment the dynamic range of the amplifiers are provided.
