AU5517

Dual operational transconductance amplifier

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

audible noise that could otherwise be heard in high quality audio

applications.
