Key Features

  • 24-bit resolution with up to 216ksps sample rate supports high-definition audio playback beyond CD and DVD quality standards
  • ±7.14V analog output voltage swing enables direct interfacing with line-level audio stages without additional gain amplification in many designs
  • Serial 2's-complement input interface provides straightforward integration with DSPs and digital audio processors in home theater and professional audio equipment

Applications

The CS4398-CZZ is designed for high-fidelity audio playback systems including AV receivers, CD and DVD players, digital audio workstations, and professional mixing consoles where 24-bit depth and up to 216ksps sampling rate deliver transparent audio reproduction. Its wide ±7.14V output swing is compatible with standard line-level signals, reducing the need for external amplification stages in consumer and pro-audio analog output paths. The 28-pin TSSOP package suits space-constrained audio module designs while maintaining the thermal performance needed for linear analog output drivers.

Frequently Asked Questions

What resolution and maximum sample rate does the CS4398-CZZ support, and how does this relate to high-definition audio formats?

The CS4398-CZZ is a 24-bit DAC supporting sample rates up to 216ksps. Standard CD audio uses 16-bit depth at 44.1ksps, while high-definition audio formats such as DVD-Audio and SACD require 24-bit at 96ksps or higher. The CS4398-CZZ's 24-bit, 216ksps capability covers all major HD audio formats and provides more than 144dB theoretical dynamic range, making it suitable for professional and audiophile-grade playback systems.

What is the analog output voltage range of the CS4398-CZZ, and how does it simplify line-level audio output stage design?

The CS4398-CZZ delivers an analog output voltage swing of -7.14V to +7.14V (14.28V peak-to-peak). Standard consumer line-level audio runs at approximately 1V RMS (2.83V peak-to-peak) while professional line-level is around 1.23V RMS. The wide ±7.14V swing means the DAC output can directly drive most downstream analog stages or be attenuated to line level without a gain stage, simplifying the analog output circuit and reducing component count.

What serial input format does the CS4398-CZZ accept, and which digital audio sources are compatible?

The CS4398-CZZ accepts a serial 2's-complement binary input format, which is the standard representation used by I2S and left-justified/right-justified audio interfaces found on DSPs, SoCs, FPGAs, and digital audio receivers. This broad compatibility means the CS4398-CZZ can be directly connected to most digital audio sources without format conversion logic, accelerating audio subsystem design in consumer electronics and professional audio gear.

What package does the CS4398-CZZ use, and what are the implications for PCB layout in audio designs?

The CS4398-CZZ comes in a 28-pin TSSOP (Thin Shrink Small Outline Package), which has a 0.65mm pin pitch and a compact body. In audio PCB layout, the TSSOP package allows the DAC to be placed close to analog output op-amps while minimizing trace lengths from the serial digital input to the IC, reducing susceptibility to digital noise coupling into the sensitive analog output section. The 28-pin count provides enough I/O for the stereo audio data, control interface, and power supply pins in a single package.
