General Description

The ft2145 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 ft2145 is capable of delivering 3.2W into to 4Ω load or 1.8W into 8Ω load, with THD+D less than 10%.

Overview

ft2145 3.2W Non-Clip Class-D Audio Power Amplifier GENERAL.

Key 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 ft2145 features high efficiency (up to 90%) and high PSRR (75dB at 217Hz), which make the device ideal for use in cellular handsets and other portable devices. APP.
