Overview

The PCM1754DBQR is a 24-bit, 192kHz stereo digital-to-analog converter (DAC) designed for high-performance audio applications. It utilizes a 4th-order noise shaper and an 8-level amplitude quantization architecture to achieve excellent dynamic performance and high tolerance to clock jitter. The device operates from a single 5V supply and supports industry-standard I2S and right-justified data formats.

Why Choose This Part

It features hardware-based control for simple integration without requiring a microcontroller software stack for basic operation. The inclusion of an integrated 44.1kHz digital de-emphasis filter and a soft mute function enhances audio quality and user experience during playback transitions. Its single 5V supply requirement simplifies power tree design in consumer electronics.

Applications

A/V Receivers
Providing high-fidelity stereo analog output for home theater and multi-channel audio systems.
Car Audio Systems
Integrating into automotive head units and external amplifiers for high-resolution audio playback.
Digital HDTVs
Converting digital audio streams to high-quality analog signals for television integrated speakers or line outputs.
DVD and Blue-ray Players
Handling high-sample rate audio decoding up to 192kHz for premium media playback.

Getting Started

Engineers can interface the PCM1754DBQR directly with an I2S master such as a DSP or SoC, ensuring the system clock (SCK) is synchronized with the sampling frequency. For rapid prototyping, use a 16-SSOP to DIP adapter board to test on a breadboard. Ensure proper decoupling of the 5V VDD supply and keep the analog output traces away from high-speed digital lines to minimize noise floor.
