LM13700
Dual Operational Transconductance Amplifiers with
Linearizing Diodes and Buffers
General Description
The LM13700 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. High
impedance buffers are provided which are especially de-
signed to complement the dynamic range of the amplifiers.
The output buffers of the LM13700 differ from those of the
LM13600 in that their input bias currents (and hence their
output DC levels) are independent of I
performance superior to that of the LM13600 in audio appli-
cations.
