Working Principles

The PCM1753DBQ operates by receiving digital audio data through its serial data input (DIN) pin. The bit clock (BCK) and word clock (LRCK) signals synchronize the data transfer. The digital audio data is then converted into analog signals using a high-precision DAC. The resulting analog signals are available at the right channel analog output (VOUTR) and left channel analog output (VOUTL) pins.

Detailed Application Field Plans

The PCM1753DBQ is widely used in various audio applications, including but not limited to: - Audio amplifiers - Home theater systems - Portable media players - Car audio systems - Professional audio equipment
