The TDA7360 is a new technology class AB Audio Power Amplifier in the Multiwatt® package designed for car radio applications. Thanks to the fully complementary PNP/NPN  output configuration the high power performance  of the TDA7360 is obtained without bootstrap  capacitors. A delayed turn-on mute circuit eliminates audible  on/off noise, and a novel short circuit protection system prevents spurious intervention with highly  inductive loads. The device provides a circuit for the detection of  clipping in the output stages. The output, an open  collector, is able to drive systems with autom…

4x45W Stereo Power Amplifier Circuit Diagram TDA8596

General description:
The TDA8596 is a quad Bridge Tied Load (BTL) audio power amplifier with symmetrical inputs, made in BCDMOS technology. It contains four independent amplifier channels in BTL configuration with complementary (PMOST/NMOST) output stages. Temperature warning and output signal clipping diagnosis is possible via the I2C-bus and via the diagnostic pins (DIAG and STB pin). The temperature pre-warning level and clip detection levels can be programmed via the I2C-bus. The status of each amplifier channel (i.e. output offset, load connected or not, short circuit condition at the output pins) can be read out separately.

The TDA1565TH is a monolithic power amplifier in a 20-lead heatsink small outline plastic package. It contains two identical 40 W amplifiers. Power dissipation is minimized by switching from SE to BTL mode only when a higher output voltage swing is needed. The device is developed primarily for car radio applications.
