CS5333-BZ - 24-Bit 96 kHz Stereo ADC | Cirrus Logic
MPN: CS5333-BZ ✓ نشطCS5333-BZ نظرة عامة
A stereo ADC is an analog-to-digital converter that accepts two simultaneous analog audio channels and produces corresponding digital sample streams. The CS5333 belongs to the broader ADC category, where resolution determines the numerical granularity of each sample, sampling rate determines how many samples are captured each second, and dynamic range describes the usable signal span relative to the converter noise floor. Its 24-bit architecture and 96 kHz maximum sampling rate support high-fidelity consumer audio systems.
The CS5333-BZ provides line-level inputs, low-power operation, and integrated delta-sigma conversion in a compact 16-pin TSSOP package. At a 3 V supply, its specified dynamic range reaches 98 dB, while the -88 dBFS THD+N figure provides a quantitative indication of distortion performance. Operation from 1.8 V to 3.3 V also supports both low-voltage portable designs and conventional 3.3 V audio subsystems.
A master-mode DIV pin provides configuration flexibility by allowing the system to select base-rate or high-rate operation according to the required conversion performance. This makes the device adaptable to different audio-clock and sample-rate arrangements. The manufacturer application note AN285REV1 discusses the timing and configuration distinctions involved in transitioning from the CS5333 to CS5340 and CS5344 designs.
Typical uses include set-top boxes, audiovisual receivers, DVD and karaoke players, and other digital audio products that require compact stereo conversion. Its line-level input architecture is particularly appropriate for consumer audio paths in which the source already provides a compatible line signal and the converter must supply accurate, high-resolution digital samples to an audio processor or decoder.
The most important design consideration is confirming that the system clock, master or slave operating mode, DIV state, analog input levels, and digital interface timing match the intended audio architecture. Use the pin-description and application-information tables in the manufacturer datasheet when assigning signals, and preserve the recommended power-supply and analog-input filtering arrangements to avoid degrading the converter's noise and distortion performance.

التطبيقات النموذجية
CS5333-BZ مناسب لـ 6 التطبيقs: Set-Top Box Audio Conversion, Audiovisual Receiver, DVD and Karaoke Player, Portable Digital Audio Device, Digital Mixing Console, Multimedia Speaker Interface.
Set-Top Box Audio Conversion
The CS5333-BZ fits a set-top box that must convert stereo line-level audio into a digital stream for downstream decoding or mixing. Its 24-bit resolution and 96 kHz maximum sample rate support high-resolution capture, while the 98 dB dynamic range at 3 V provides useful headroom above the converter noise floor. The device accepts a 1.8 V to 3.3 V supply and consumes 11 mW at 1.8 V, helping limit power demand in compact consumer electronics. Place the analog inputs behind the filtering and routing network recommended by the manufacturer, then confirm the master or slave clock arrangement and DIV setting against the audio processor timing requirements.

Audiovisual Receiver
In an audiovisual receiver, the CS5333-BZ can digitize stereo line-level sources before format conversion, level control, or surround-sound processing. Its dual-channel delta-sigma architecture handles left and right inputs, while 24-bit resolution preserves fine amplitude detail and the 96 kHz maximum rate supports high-rate audio streams. The 16-pin TSSOP package is useful when receiver boards must combine multiple signal functions in a constrained area. Engineers should verify the receiver's required master clock, digital interface timing, and supported master-mode configuration, using the DIV pin to select the appropriate operating speed.

DVD and Karaoke Player
The CS5333-BZ is appropriate for DVD and karaoke-player analog audio paths that require stereo line-level digitization within a compact board. Its 24-bit, 96 kHz conversion supports high-fidelity capture from source circuitry, and the -88 dBFS THD+N specification provides a defined distortion target for design verification. Operation from 1.8 V to 3.3 V accommodates both portable-oriented and 3.3 V system rails, while 11 mW consumption at 1.8 V supports low-power operation. Confirm startup behavior, clock source, and input-filter topology before releasing the PCB because related Cirrus Logic converters may differ in these details.

Portable Digital Audio Device
A portable digital audio product can use the CS5333-BZ to convert stereo line-level audio while maintaining a compact, low-power design. The 1.8 V minimum supply allows operation from a low-voltage system rail, and the 11 mW consumption figure at 1.8 V helps designers allocate power for analog and digital subsystems. A 24-bit resolution and 96 kHz maximum sample rate provide a useful specification balance for high-quality playback or recording paths. The 16-pin TSSOP package must be checked against the available board area, while the supply decoupling and analog-input filtering should follow the manufacturer layout recommendations.

Digital Mixing Console
The CS5333-BZ can serve as the stereo capture converter in a digital mixing console that accepts line-level inputs from instruments, media players, or monitoring equipment. Its 24-bit resolution supports detailed sample representation, and the dual input architecture reduces the need for separate converters for the left and right channels. The 98 dB dynamic range at 3 V and -88 dBFS THD+N figures support initial performance budgeting for a mixer signal chain. Before layout release, validate the required sample rates, audio master clock, serial interface timing, and whether base-rate or high-rate operation selected through DIV matches the console's processing architecture.
موصى به
Multimedia Speaker Interface
The CS5333-BZ is usable when a multimedia speaker interface must capture stereo analog levels before passing them to a digital signal processor. Its line-level input arrangement suits conventional consumer-audio sources, while 24-bit conversion at up to 96 kHz supports detailed digital processing. The device's 1.8 V to 3.3 V operating range allows integration into multiple system architectures, and the 16-pin TSSOP package simplifies routing compared with a larger converter package. The design must still account for input coupling, grounding, supply decoupling, and clock quality because these implementation details directly influence the realized noise and distortion performance.

ملاحظات التصميم
Use the 1.8 V to 3.3 V operating range as the basis for supply selection, and reserve local high-frequency bypass capacitors close to the device supply pins. The converter consumes 11 mW at 1.8 V, but total board consumption also depends on sample rate, clock mode, and external circuitry. Keep analog and digital return currents separated where possible so switching current from surrounding logic does not add noise to the line-level input path.
Place analog input traces away from digital clock and serial-interface traces, and follow the routing shown in the manufacturer datasheet or application guidance. Keep the input filtering components close to their associated pins to minimize pickup between the converter and its source. Use a compact ground-return strategy under the analog section, and avoid routing the master clock beneath the analog input area when a different topology is electrically acceptable.
Do not assume that another stereo ADC with similar resolution is a drop-in replacement. Related Cirrus Logic devices can differ in startup mode, system clocking, input-filter topology, reference-pin decoupling, and pin functions, as discussed in application note AN285REV1. Before substituting a converter, compare the package drawing, every power pin, clock direction, data interface, DIV behavior, acquisition timing, and analog input range.
Confirm whether the CS5333-BZ operates as clock master or slave and choose the DIV state only after determining the required sample rate and clock relationship. The manufacturer guidance states that DIV high selects base-rate mode and DIV low selects high-rate mode in master mode. A mismatched clock configuration can produce incorrect timing or conversion-rate operation even when the analog input and supply connections are correct.
