Introduction
STA516B
The STA516B is a high performance quad half-bridge amplifier with the capability to drive up
to 220 W (a) stereo into 3- to 8-ohm speakers from a single 50 V supply.
It offers the highest flexibility since it can be configured as a stereo-BTL, as a mono-BTL or
as four channels of single-ended outputs to fit different application requirements.
It provides remarkably high levels of efficiency when driven by the FFX-patented 3-state
pulse-width modulator embedded in STMs digital audio processors .
The device is self-protected by design. Overcurrent, overtemperature, under- and
overvoltage protection are provided with an automatic recovery feature to safeguard the
device and speakers against fault conditions that could damage the overall system.

a. The achievable output power depends on the thermal configuration of the final application.
A high performance thermal interface material between the package exposed pad and the heat sink should be
used in order to maximize output power levels
