YDA144

The Yamaha YDA144 is a digital audio power amplifier designed for stereo applications, delivering up to 2.1W of output power. This component integrates advanced features such as non-clip control and dedicated shut-down terminals for both left (Lch) and right (Rch) channels, allowing for precise management of audio output and power saving.

The YDA144 is available in two surface-mount package types: WLCSP16 and QFN20. These compact packages are suitable for space-constrained designs. The amplifier supports various input and output configurations, including differential inputs for improved signal integrity and direct output terminals. Its design aims to provide high-quality audio amplification with efficient power management.

Key electrical characteristics include its ability to operate as a stereo amplifier with a nominal output of 2.1W. The inclusion of gain setting terminals offers flexibility in adjusting amplification levels. The device also incorporates protection circuits on its analog input terminals to safeguard against overvoltage conditions.

This audio power amplifier is suitable for a range of audio applications where compact size, power efficiency, and reliable performance are critical. Its features facilitate integration into portable audio devices, multimedia systems, and other consumer electronics requiring integrated audio amplification.
