PCM1754DBQR 24-bit Audio DAC High-Fidelity 192kHz Sampling Rate
The PCM1754DBQR is a high-performance, 24-bit stereo audio digital-to-analog converter (DAC) from Texas Instruments (TI), designed for premium audio applications. It features Delta-Sigma modulation with 4th-order noise shaping and 8-level amplitude quantization, delivering 106dB SNR and ultra-low distortion (THD+N: 0.002%). Operating on a 5V supply, it supports sampling rates up to 192kHz and offers hardware/software control modes via a 3-wire serial interface. Packaged in a compact SSOP-16 (150mil) form factor, it is RoHS-compliant and operates across an industrial temperature range (-40°C to 85°C).
TI Stereo DAC Key Features & Performance
The PCM1754DBQR excels with 24-bit resolution, dual-channel output, and low power consumption (80mW). Its enhanced dynamic range (106dB) and low noise floor ensure high-fidelity audio reproduction, while integrated digital filters (4×/8× oversampling) minimize aliasing. The DAC supports I²S, left/right-justified audio formats and includes soft mute, zero-flag detection, and 44.1kHz de-emphasis. The single 5V power supply simplifies design, and its small footprint (5mm × 4mm) suits space-constrained applications.
Applications & Industry Use Cases
This DAC is ideal for high-end audio systems, including A/V receivers, HDTVs, automotive sound systems, and professional audio equipment. It is also used in digital audio workstations, home theater amplifiers, and portable media players due to its low distortion and high SNR. Additionally, its robust performance in industrial environments makes it suitable for medical audio devices and instrumentation requiring precision signal conversion.
Why Choose PCM1754DBQR?
The PCM1754DBQR offers superior audio clarity, ease of integration, and flexible control options (hardware/software modes). Compared to alternatives, it provides better jitter tolerance and lower power consumption than many legacy DACs. Its compatibility with industry-standard interfaces (I²S, SPI) ensures seamless integration with DSPs and microcontrollers. For cost-sensitive designs, PCM1753DBQ or PCM1755DBQ serve as functional alternatives, though with minor trade-offs in performance .
Alternative & Replacement Options
For design flexibility, TI offers several pin-compatible substitutes:
1. PCM1753DBQ: Similar 24-bit DAC but with slightly lower sampling rates.
2. PCM1755DBQ: Higher-end variant with improved dynamic range.
3. PCM1754DBQ: Nearly identical but with different packaging (Tube vs. Tape & Reel) .
