NOS USB TDA1543

About the NOS USB TDA1543

The Valab NOS USB DAC TDA1543 employs the Philips TDA1543 dual 16-bit DAC chip, known for its economy and simplicity in hi-fi digital audio equipment. This DAC uses a non-oversampling (NOS) design, which bypasses digital filtering to produce a distinct sound character favored by some audiophiles. It accepts I2S input format and operates on a single 5V power supply. The TDA1543 chip features low distortion, 16-bit dynamic range, and internal timing and control circuits, requiring no external deglitcher circuitry. The Valab DAC integrates this chip with a USB to I2S interface, enabling direct USB audio input. While the TDA1543 is an older DAC chip originally designed in the early 1990s, it remains popular for its musicality and simplicity, often enhanced by external analog stage improvements such as tube buffering. The Valab NOS USB DAC TDA1543 is suitable for multimedia systems, satellite radio, CD players, and DVD audio applications, offering a vintage DAC experience with modern USB connectivity.
