常見問題解答

What is PCM1702U-K?

The PCM1702U-K is a 20-bit digital-to-analog converter (DAC) manufactured by Texas Instruments. It is designed to provide high-quality audio output for professional and consumer audio applications, such as digital audio workstations, audio interfaces, and high-fidelity audio systems.

How Does PCM1702U-K Work?

The PCM1702U-K works by converting digital audio data into analog voltage signals with high precision and dynamic range. It utilizes a multi-level delta-sigma architecture and advanced digital filtering to achieve high signal-to-noise ratio and low total harmonic distortion, resulting in high-fidelity audio output.

How Many Pins does PCM1702U-K have and What are the Functions of the Pinout Configuration?

The PCM1702U-K is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:

VOUTL, VOUTR: Analog audio output pins for the left and right audio channels, respectively.
VCOM: Common voltage output pin.
DOUT: Serial data input pin for the digital audio data.
LRCK: Left/right serial audio data word clock input pin.
BCK: Serial audio data bit clock input pin.
MUTE: Mute control input pin.
VREF: Reference voltage input pin.
VCC, DGND: Power supply and digital ground pins, respectively.

What are the Pros and Cons of PCM1702U-K?

Pros:
