The TDA7053A from Philips is a stereo BTL audio output amplifier designed for applications such as TVs, monitors, and battery-fed portable devices. It features DC volume control, allowing for precise adjustment without external potentiometers.
Key electrical specifications include a supply voltage range of 4.5V to 18V. The amplifier can deliver up to 1W of output power into an 8-ohm load at 6V supply. It offers a typical voltage gain of 40.5 dB and a total quiescent current of 25 mA at 6V supply. Total harmonic distortion is kept low, typically 0.3% at 0.5W output.
Designed for ease of use, the TDA7053A requires few external components and includes features such as mute mode, thermal protection, and short-circuit proofing. It also provides no switch-on and switch-off clicks, ensuring a clean audio experience. The device is available in DIP16 and SO16 packages.
