Showing posts with the label TDA8925

Power stage 2 x 15 to 25 W class-D

FEATURES:
High efficiency (> 94 %) Operating voltage from ±7.5 V to ±30 V Very low quiescent current High output power Diagnostic output Usable as a stereo Single-Ended (SE) amplifier Electrostatic discharge protection (pin to pin) No heatsink required.
APPLICATIONS:
Television sets Home-sound sets Multimedia systems All mains fed audio systems.
GENERAL DESCRIPTION:
The TDA8925 is a switching power stage for a high efficiency class-D audio power amplifier system. With this power stage a compact 2 × 15 W self oscillating digital amplifier system can be built, operating with high efficiency and very low dissipation. No heatsink is required. The system operates over a wide supply voltage range from ±7.5 V up to ±30 V and consumes a very low quiescent current.
