General Description: The TA2024C is a 15W/ch continuous average two-channel Class-T Digital Audio Power Amplifier IC   using Tripath’s proprietary Digital Power Processing™ technology. Class-T amplifiers offer both the  audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.  The TA2024C has incorporated specific changes to improve the click and pop performance over   previous devices such as TA2024 and TA2024B. The TA2024C is recommended for all new designs   that previously used the TA2024 or TA2024B. Circuit Diagram: Stereo 15W CLASS-T Digital 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). 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 Applicat...

General description The TDA8931 is a switching power stage for high efficiency class-D audio power amplifier  systems.  It contains a Single-Ended (SE) power stage, drive logic, protection control logic, a full  differential input comparator and a HVP charger to charge the SE capacitor. With this  amplifier a compact 1 × 20 W closed loop self-oscillating digital amplifier system can be  built. The TDA8931 has a high efficiency so that a heat sink is not required up to  20 W (RMS). The system operates on an asymmetrical and a symmetrical supply voltage. Features High efficiency Operating voltage asymmetrical from 12 V to 35 V Operating voltage symmetrical from ±6 V to ±17.5 V Thermally protected No heat sink required Charger for single-ended capacitor No pop sound Applications Flat panel television sets Flat panel monitors Multimedia systems Wireless speakers Micro systems Circuit Diagram 20W power amplifier TDA893...
