For the higher output power range, ST offers its latest generation of digital audio power amplifiers, based on our FFX technology. Combining all-digital and high-efficiency full flexible amplification, ST's audio power solutions can be used in a wide range of consumer audio products and offer the following features:
- Binary and ternary FFX high-efficiency operating modes
- Flexible configuration possible between 1.0, 2.0, 2.1 and 4.0 channels
- PSO36 and PSS036 surface mount slug up and down packaging for optimal heat dissipation
STA518 quad power half-bridge digital audio amplifier
The device is particularly designed to make the output stage of a stereo All-Digital High Efficiency (DDX™) amplifier capable to deliver an output power of 24W x 4 channels @ THD = 10% at Vcc 30V on 4W load in single ended configuration. It can also deliver 50 + 50W @ THD = 10% at Vcc 29V as output power on 8W load in BTL configuration and 70W @ THD = 10% at Vcc 34V on 8W in single paralleled BTL configuration.
