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

Leave a Comment
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

Leave a Comment
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).

Features

Operating voltage from 10 V to 36 V asymmetrical or ±5 V to ±18 V symmetrical
Mono-bridged tied load (full-bridge) or stereo single-ended (half-bridge) application
Application without heat sink using thermally enhanced small outline package
High efficiency and low-power dissipation
Thermally protected and thermal foldback
Current limiting to avoid audio holes
Full short-circuit proof across load and to supply lines (using advanced current protection)
Switchable internal or external oscillator (master-slave setting)
No pop noise
Full-differential inputs

Applications

Flat panel television sets
Flat panel monitor sets
Multimedia systems
Wireless speakers
Mini and micro systems
Home sound sets
