Working Principles

The UDA1342TS/N1,518 operates by receiving digital audio data through the serial data input (SDIN) pin. The internal circuitry processes the digital audio signal, including sampling, quantization, and filtering. The processed audio is then converted into analog form through the digital-to-analog converters (DACOUTL and DACOUTR). The resulting analog audio signals can be further amplified and used for various audio applications.

Detailed Application Field Plans

The UDA1342TS/N1,518 is suitable for a wide range of audio applications, including but not limited to: - Portable audio devices - Automotive audio systems - Home entertainment systems - Professional audio equipment - Telecommunications devices
