STA516BE-500 W FFX digital amplifier power stage
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.
