60 W Quad Half-Bridge Digital Amplifier

General Description: The CS44130 is a high-efficiency power stage for digital Class-D amplifiers designed to recieve PWM signals from a modulator such as the CS44800/600. The power stage outputs can be configured as four half-bridge channels, two half-bridge channels and one full-bridge channel, two full-bridge channels, or one parallel full-bridge channel. Features:  Configurable Outputs (10% THD+N) – 2 x 30 W into 8 Ω, Full-Bridge – 1 x 60 W into 4 Ω, Parallel Full-Bridge – 4 x 15 W into 4 Ω, Half-Bridge – 2 x 15 W into 4 Ω, Half-Bridge + 1 x 30 W  into 8 Ω, Full-Bridge  Space-Efficient, Thermally-Enhanced QFN  Package  PWM Popguard® Technology for Quiet Startup  > 100 dB Dynamic Range - System Level  < 0.12% THD+N @ 1 W - System Level  Built-In Protection with Error Reporting – Over-Current – Thermal Warning – Thermal Fault – Under-Voltage  Single (+10.8 V to +21 V) High Voltage Supply  High Efficiency (90%)  Low RDS(ON)  Low Quiescent Current  Low Power Standby Mode Common Applications  …

4 x 49 W quad bridge car radio amplifier

General Description:
The TDA7386 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed  for high end car radio applications. Based on a fully complementary PNP/NPN  configuration, the TDA7386 allows a rail to rail  output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.
