NE5517中文资料安森美半导体数据手册PDF规格书

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.
