STMicroelectronics Digital Audio System-On-Chip Packs 2x20W In Tiny Footprint

imagesMeasuring just 2.57mm x 3.24mm yet delivering up to 2x20W of audio output power, the STMicroelectronics STA333IS is the most power dense single-chip digital audio system available today and extends ST’s SoundTerminal™ family, combining advanced process and chip-scale package technologies with digital audio IPsuch as ST’s proprietary FFX full flexible amplification.

The STA333IS is unique in the marketplace, since only ST has the technologies and audio IP (Intellectual Property) to combine advancedsignal processing and power circuitry on a single chip. With its wide operating voltage range, from 4.5V to 18V, it is ideal for battery-operated equipment as well as space-constrained products such as LCD or LED televisions, docking stations and digital wireless speaker systems.

The STA333IS delivers superb audio quality that goes hand in hand with outstanding thermal efficiency andlow electromagnetic emissions, and the tiny 8.3mm2 footprint gives extra freedom to style new generations of audio products.

Also available, the STA333SML variant for “micro-less” applications operates without an external microcontroller, enabling designers to create digital amplifiers with the lowest cost of ownership.

Samples and production quantities of the STA333IS and STA333SML areavailable now as 5×6-bump 0.5mm-pitch Chip-Scale Package (CSP) devices, priced from $1.00 for orders over 1,000 pieces.
