TDA7560 Audio Amplifier 4x50W

TDA7560general description:

TDA7560 is a 4 x 45W QUAD BRIDGE car audio amplifier plus HSD. The TDA7560’s inputs are ground-compatible and can stand very high input signals (± 8Vpk) without any performances degradation. If the standard value for the input capacitors (0.1mF) is adopted, the low frequency cut-off will amount to 16 Hz. The TDA7560 is a breakthrough BCD (Bipolar / CMOS / DMOS) technology class AB Audio Power Amplifierin Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimised saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.

High Efficiency Power Amplifier 2 x 30W into 8Ω or 1 x 60W into 4 Ω

GENERAL DESCRIPTION
The DDX-2050 power device is a monolithic dual channel H-Bridge that can provide up to 30 watts  per channel of audio power at very high efficiency. The DDX-2050 power device  contains a logic interface, integrated bridge  drivers, high efficiency MOSFET output  transistors and protection circuitry. The device  may be used as a dual bridge or reconfigured as  a single bridge with double the output current  capability.  The benefits of the DDX amplification system are  an all-digital design that eliminates the need for a  digital to analog converter (DAC) and the high  efficiency operation derived from the use of  Apogee's patented damped ternary pulse width  modulation (PWM). This approach provides an  efficiency advantage over conventional Class-D  designs and up to three times the efficiency of  typical Class A/B amplifiers with music input  signals.

TDA8932B Class-D audio amplifier

General description
The TDA8932B is a high efficiency class-D amplifier with low power dissipation. The continuous time output power is 2 × 15 W in stereo half-bridge application (RL = 4 Ω) or 1 × 30 W in mono full-bridge application (RL = 8 Ω). Due to the low power dissipation the device can be used without any external heat sink when playing music. Due to the implementation of thermal foldback, even for high supply voltages and/or lower load impedances, the device continues to operate with considerable music output power without the need for an external heat sink. The device has two full-differential inputs driving two independent outputs. It can be used in a mono full-bridge configuration (BTL) or in a stereo half-bridge configuration (SE).
