STMicroelectronics today announced their new model STA510Famplifier.

The STA510F is intended particularly to match other family devices that use ST’s proprietary FFX (full flexible amplification) digital modulation technology, but is sufficiently flexible to also accept signals from other drivers using any PWM modulation scheme, such as ternary, phase shift or binary. The amplifier preserves the full audio quality of the PWM input signal, providing a cost-effective output stage for demanding but price- sensitive applications such as home theatre and cinema systems, and mini- and micro-component audio systems.

In addition, the STA510F simplifies design and reduces the bill-of-materials (BOM) cost by integrating the circuitry required for the critical turn-off sequence of the logic- and power-stage power supplies; ST’s patented ‘easy start’ scheme eliminates the requirement for accurate control of the power-down sequence using external circuitry, thus ensuring ease of use for audio system manufacturers, and increased reliability.

The new amplifier is manufactured using ST’s state-of-the-art BiCMOS-DMOS process technology, which allows the integration of DMOS power, Bipolar and CMOS structures on the same chip. It is an ideal companion for the new STA330, a 2.0 channel PWM controller based on ST’s FFX technology, and the STA331, a highly efficient and versatile FFX audio processor
coupled with an ARM7TDMI(R) core.

The STA510F is currently being sold to retailers in bulk, so look for it soon in retail locations.
