NE5517A Datasheet Dual Operational Transconductance Amplifier

Manufacturer: onsemi

Overview: Dual Operational Transconductance Amplifier NE5517 The NE5517 contains two current-controlled transconductance amplifiers, each with a differential input and push-pull output. The 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 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 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.

This datasheet includes multiple variants, all published together in a single manufacturer document.
