NE5517_13 Datasheet, PDF (1/15 Pages) ON Semiconductor – Dual Operational Transconductance Amplifier

NE5517, NE5517A, AU5517
Dual Operational
Transconductance Amplifier
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 of the 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 I_ABC, hence eliminating
the audible noise that could otherwise be heard in high quality audio
applications.
