ft2012 The ft2012 is a 2.1W/ch stereo high efficiency filter-free class-D audio power amplifier. The ft2012 can operate from 2.7 to 5.5V supply. When powered with 5V voltage, the ft2012 can deliver 2.1W per channel to dual 4Ω load at 10% THD+N, and also capable of driving 1.5W/ch to dual 8Ω load. The ft2012 is thermally limited in WCSP and may not achieve 2.1W/ch for 4Ω. As a Class D audio power amplifier, the ft2012 supports 90% high efficiency and -75dB PSRR at 217Hz which make the device ideal for battery-supplied, high quality audio applications. The ft2010 features independent shutdown controls for each channel. The gain can be selected to 6, 12, 18, or 24 dB utilizing the G0 and G1 gain select pins. The ft2012 also features the minimized click-and-pop noise during the turn-on and shutdown.
