Mono Class D Audio Power Amp has filter-less capability.(AAT 5101 / 2.5W Mono Filter-Free Class D Audio Power Amplifier)
Supplied in 9-pin WLCSP, single-channel AAT5101 employs low-noise, filterless PWM architecture that eliminates output filter and reduces external component count in cellular phones and PDAs. It operates from 2.1-5.5 V, and output capabilities include 1.35 W with 8x load and 2.5 W with 4x load. In addition to pop and click noise suppression circuitry, 0.12% THD+N @ 5 V and 91 dB SNR values ensure clean sound across audio output power range and full audio frequency domain.
********************
The AAT5101 is a high efficiency, 2.5W mono class D audio power amplifier. The low noise, filterless PWM architecture eliminates the output filter, reduces the external component …
