Description
The PCM1754DBQR is a 24-bit, 96 kHz stereo digital-to-analog converter (DAC) from Texas Instruments. It features delta-sigma modulation for high-fidelity audio output and supports I2S, left-justified, and right-justified digital input formats. Operating at 5V, it delivers low distortion (THD+N: 0.002%) and high dynamic range (106 dB).
Key features:
- Single 5V supply
- On-chip digital filter & analog output
- Low power consumption (50 mW typical)
- Small TSSOP-16 package
Ideal for CD/DVD players, digital TVs, and audio systems, the PCM1754DBQR provides high-performance audio conversion with minimal external components.
