DESCRIPTION
The AU5517 and NE5517 contain two current-controlled
transconductance amplifiers, each with a differential input and
push-pull output. The AU5517/NE5517 offers significant design and
performance advantages over similar devices for all types of
programmable gain applications. Circuit performance is enhanced
through the use of linearizing diodes at the inputs which enable a
10 dB signal-to-noise improvement referenced to 0.5% THD. The
AU5517/NE5517 is suited for a wide variety of industrial and
consumer applications.
Constant impedance buffers on the chip allow general use of the
AU5517/NE5517. These buffers are made of Darlington transistors
and a biasing network that virtually eliminate the change of offset
voltage due to a burst in the bias current IABC, hence eliminating the
audible noise that could otherwise be heard in high quality audio
applications.
