$Features & Applications

Austriamicrosystems designs, manufactures and markets high performance analog integrated circuits for communications, industrial, medical and automotive markets building on more than 25 years of analog design capabilities, system know-how, and own state-of-the-art manufacturing and test facilities.

Austriamicrosystems’ focuses on power management, sensors & sensor interfaces, portable audio and car access applications, and offers the industry's broadest range of high performance absolute and incremental rotary and linear magnetic encoder devices that are complete SoC solutions integrating Hall element, analog front end and digital signal processing.

The AS1702 - AS1705 are single-channel differential audio power-amplifiers designed to drive 4 and 8Ω loads. The integrated gain circuitry of these amplifiers and their small size make them ideal for 2.7- to 5V-powered portable audio devices.

The differential input design improves noise rejection and provides common-mode rejection. A bridge-tied load (BTL) design minimizes external component count,

while providing high-fidelity audio power amplification.

The devices deliver 1.8W continuous average power per channel to a 4Ω load with less than 1% total harmonic distortion (plus noise), while operating from a single 2.7 to 5V supply.

For reduced component designs, the devices are available with different gain levels. Integrated shutdown circuitry disables the bias generator and amplifiers, and reduces quiescent current consumption to less than 100nA. The shutdown input can be set active-high or active-low. All devices contain clickand-pop suppression circuitry that reduces audible clicks and pops during power-up and shutdown.

The AS1702 is ideal as audio front-ends for battery powered audio devices such as MP3 and CD players, mobile phones, PDAs, portable DVD players, and any other hand-held battery-powered device.

The AS1702Z is offered in an adjustable gain option in a 10-pin MSOP package with a temperature range of -40 ºC to +85ºC.
