Digital audio SoC boasts 2x20W of audio output power

STMicroelectronics recently debuted the STA333IS, a power dense single-chip digital audio system that extends the SoundTerminal Family. The chip combines advanced process and chip-scale package technologies with digital audio IP, such as the FFX full flexible amplification. The device also comes in a 57x3.24mm package while delivering up to 2x20W of audio output power.

With its wide operating voltage range, from 4.5V to 18V, the STA333IS 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 and low 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 are available now as 5x6-bump 0.5mm-pitch Chip-Scale Package (CSP) devices, priced from $1.00 for orders over 1,000 pieces.
