Frequently Asked Questions
What resolution and sample rate does the PCM1704U DAC support?
The PCM1704U is a 24-bit dual-channel DAC operating at up to 96 kSPS sample rate with ±3%FSR accuracy. This resolution and speed support high-fidelity audio reproduction well above the 16-bit 44.1 kSPS CD standard, making it suitable for professional and audiophile playback systems.
What supply voltage does the PCM1704U require and how does the negative supply affect the circuit design?
The PCM1704U requires a -5 V negative supply voltage alongside a positive supply rail. The negative supply enables true bipolar analog output swing, which is essential for direct-coupled audio output stages in high-fidelity DAC designs without output coupling capacitors that could affect low-frequency response.
Which audio systems benefit from using PCM1704U instead of a 16-bit DAC?
High-end CD players, SACD transports, and professional digital mixing consoles benefit from the PCM1704U's 24-bit depth compared to 16-bit alternatives. The additional 8 bits provide over 48 dB of extra dynamic range headroom, allowing finer volume gradations and lower noise floor in critical listening environments.
How is PCM1704U connected to an audio DSP for a stereo playback design?
The PCM1704U receives 24-bit serial data in 2's complement binary format, compatible with standard I2S or left-justified serial audio interfaces from DSPs and digital receivers. Two channels in a single 20-pin SOP handle left and right audio simultaneously, simplifying the PCB layout for stereo designs.
