LM13600AN Dual Operational Transconductance Amplifiers with Linearizing Diodes and Buffers
General Description
The
LM13600AN series consists of two current controlled
transconductance amplifiers each with differential inputs and
a 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.
