Frequently Asked Questions
What is the PCM1704U-K and how does it differ from PCM1704U?
The PCM1704U-K is TI's audio-grade (K-spec) variant of the PCM1704U 24-bit sign-magnitude DAC. The K suffix designates tighter SNR and THD+N performance selection — guaranteed ≥120dB SNR and ≤-100dB THD+N — making it preferred for audiophile and high-end professional audio applications over the standard U grade.
What supply voltage and sample rates does the PCM1704U-K support?
The PCM1704U-K operates from a single +5V analog supply with a separate digital supply of 3.3V or 5V. It accepts PCM audio data over an I2S or left-justified serial interface and supports sample rates from 8kHz up to 192kHz, covering CD, DVD-Audio, and high-resolution audio formats.
What are common alternatives to the PCM1704U-K?
Common alternatives include the PCM1704U (standard grade, same pinout), ES9038PRO (32-bit, I2S/DSD, lower THD+N), and AK4490EQ (32-bit, I2C control, QFN-48). For cost-sensitive designs, the PCM1794A in DIP-28 offers 24-bit resolution with 127dB SNR at a lower price point.
Is the PCM1704U-K RoHS compliant and what is its lifecycle status?
Yes, the PCM1704U-K is RoHS compliant and lead-free. Texas Instruments lists it as active status. For long-term production planning, verify current product status on the TI website, as high-end audio DAC ICs can transition to NRND over time.
What package and pin count does the PCM1704U-K use?
The PCM1704U-K comes in a DIP-24 (Dual In-line Package, 24 pins) through-hole package with 2.54mm pitch. The through-hole format makes it popular for audiophile DIY and prototype boards where soldering convenience and replaceability are important.
