Product details
Product Introduction
The DF1704E is typically positioned between a digital audio source (receiver, DSP, or processor) and a DAC. By applying interpolation and oversampling, it helps shape the digital signal prior to conversion, which can reduce image components and relax analog reconstruction filter requirements.
This device is often found in higher-end audio products where designers prioritize stable digital filtering, consistent behavior and proven reference-style architectures. It is a practical choice when maintaining an existing design platform or servicing legacy but still widely deployed audio systems.
The SSOP-28 package supports compact PCB layouts while keeping assembly accessible for standard SMD manufacturing processes.
Key Benefits
Provides digital interpolation/oversampling prior to the DAC stage, helping designers achieve smoother reconstruction behavior and easier analog filter design in many audio architectures.
Used in mature, validated audio signal chains where predictable digital filtering is required. This can reduce development effort for products that prioritize stable, repeatable sound characteristics.
Multiple ordering options (tape/reel, RoHS suffix) enable production-friendly procurement strategies while maintaining compatibility with validated footprints.
SSOP-28 supports dense audio boards and reduces routing burden compared to larger packages, benefiting soundcards, DAC modules and space-constrained audio products.
Technical Features
Performs digital filtering functions used ahead of DAC conversion. The exact system benefit depends on the selected DAC, clocking strategy and analog output filter design.
Commonly integrated with digital audio receivers and DACs in modular designs. Helps designers maintain clean digital signal conditioning while keeping the analog path simpler.
SSOP packaging is widely supported for mass production and rework processes, making it suitable for both consumer electronics and professional audio equipment builds.

Equivalent & Manufacturer Information
Based on your reference, the following options are commonly considered pin-to-pin or direct ordering variants of DF1704E. Always verify suffix differences (RoHS, packing quantity).
In substitution, confirm the same footprint, the same functional mode support in your design, and matching ordering constraints (tape/reel vs tray) to avoid production issues.
Texas Instruments has a long history in digital audio ICs, codecs, receivers and audio signal-chain components. Many audio platforms built around TI digital audio blocks are valued for stable supply, documentation, and reference design availability.
For audio filtering and SRC solutions, engineers often evaluate long-term availability and system-level clocking compatibility as key sourcing and design stability factors.
Application
Interpolation stage used ahead of DAC conversion for stable performance.
Premium consumer audio where consistent digital filtering is required.
Audio processing chains for studio equipment and converters.
Used when supporting existing validated designs considered stable in production.
