1W Low-EMI Filterless High-Performance Class D Audio Power Amplifier
The KTAA01301 is a high-performance monolithic class D audio power amplifier. The KTAA01301 is capable of providing better than 0.1% THD+N class AB amplifier performance with superb class D efficiency at 95%, conserving board space and extending battery life. The class D amplifier requires a single 1.8V supply and delivers 1.2W into an 8Ù speaker or 2.4W into a 4Ù speaker.
The KTAA01301 features a reliable on-chip short-circuit protection and de-popping circuit that eliminates the popping and clicking sound at turning on/off the audio.
The KTAA01301 is fabricated and verified on standard 0.25um CMOS process in HHNEC and can be directly transferred to Jazz, SMIC, TSMC and other general 0.25um or 0.18um CMOS processes.
Thanks to its high-efficiency, the product can be packaged in a variety of low cost generic 8~12-pin packages with no special thermal requirement. The test chips are available in KT Micro standard 48-pin TQFP IC evaluation package with most of pins unused. The evaluation boards and kits are available upon request.
