Datasheet Summary
3.4W Non-Clip Class-D Audio Power Amplifier
GENERAL DESCRIPTION
The ft2146 is a mono, non-clip, filterless, Class-D audio power amplifier. It operates from 2.7V to 5.5V supply. When powered with 5V supply voltage, the ft2146 is capable of delivering 3.4W into to 4Ω load or 1.8W into 8Ω load, with THD+D less than 10%.
The ft2146 Features a non-clip output control which detects the output clip caused by the over-level input signal and automatically adjusts the dynamic range of the output signal to prevent the distortion of the audio signal. The non-clip output control also eliminates the output clip due to a low battery supply voltage.
As a Class-D power amplifier, the ft2146...
