STA510F Digital Audio Power Amplifier - STMicroelectronics

STMicroelectronics announced the STA510F Digital Audio Power Amplifier. The new quad, half bridge power amplifier preserves the full audio quality of the PWM input signal, providing a cost-effective output stage for applications such as cinema and home theatre systems. The new audio amplifier is able to drive up to 100 watts per channel of audio into stereo 8-ohm loads. The device will also drive 4 x 50W into 4 ohms, or up to 200W in a mono-aural configuration.

STMicroelectronics’ STA510F Audio Digital Power Amplifier - Typical Application

Key features of STA510F Audio Power Amplifier :

• Minimum input output pulse with distortion
• CMOS compatible logics inputs
• 150 mW Rdson complementary DMOS output
• Under voltage protection
• Thermal protection and warning output
• No power-on, power-off sequence required

The STA510F Digital Audio Power Amplifier 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 STA510F Digital Audio Power Amplifier 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 STA510F Digital Audio Power Amplifier is available  in a PSO36 package. Its price is $3.00 (100K unit qty).
