Class D amplifiers have become a popular audio amplifier topology due to their high efficiency and subsequent low cost. The high current output stage is implemented using binary switches, resulting in ...

Our digital in audio amplifier family (TFA9881/TFA9882/..) is built to simplify the audio architecture in mobile phones and portable applications by lowering the system cost and enabling easy ...

Each fully differential amp channel is actually two separate channels, each driving either the positive or negative signals, with the signal bridged at the output as seen in the block diagram above.
