ST STA516BETR

The STA516BE is a monolithic quad half-bridge stage in multipower BCD technology. The device can be used as dual-bridge or reconfigured, by connecting pin CONFIG to pins VDD, as a single-bridge with double-current capability or as a half-bridge (binary mode) with half-current capability. A cost-effective, high fidelity audio system can be designed using ST chipset, including a modulator (e.g. the STA309A or STA321) and the STA516BE. This system only requires a simple passive LC demodulation filter to deliver high-quality, high efficiency audio amplification with prove EMI compliance. The efficiency of this digital amplifier is greater than 90% into 8 Ω speakers, enabling the use of smaller power supplies and heatsinks. The STA516BE has an innovative integrated protection system, safeguarding the device against different fault conditions that could damage the overall system.
