Stereo 15W CLASS-T Digital Audio Amplifier

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.

15 W mono Bridge Tied Load (BTL) audio amplifier

General description
The TDA8945S is a single-channel audio power amplifier with an output power of 15 W at an 8 Ω load and an 18 V supply. The circuit contains a Bridge Tied Load (BTL) amplifier with an all-NPN output stage and standby/mute logic. The TDA8945S comes in a 9-lead single in-line (SIL) power package. The TDA8945S is printed-circuit board (PCB) compatible with all other types in the TDA894x family. One PCB footprint accommodates both the mono and the stereo products.
Features
Few external components Fixed gain Standby and mute mode No on/off switching plops Low standby current High supply voltage ripple rejection Outputs short-circuit protected to ground, supply and across the load Thermally protected Printed-circuit board compatible.
Applications
Mains fed applications (e.g. TV sound) PC audio Portable audio.
