CS5330A-BSZ 概述
A sigma-delta ADC is a type of oversampling converter that pushes quantization noise far above the audio band and shapes it with a digital low-pass filter, producing high dynamic range from a compact analog front end. In the broader taxonomy the CS5330A-BSZ sits within audio ADCs, then data converters, then signal chain ICs, then semiconductors; it is the audio counterpart to the CS5331A family for designers who need a simple stereo digitizer without an external anti-alias filter.
Key features include 94 dB dynamic range, linear-phase digital anti-alias filtering, 18-bit resolution, single +5 V power supply operation, and a serial left-justified output format. The output sample rate is continuously adjustable from 2 kHz to 50 kHz, allowing the same hardware to support multiple audio standards including 44.1 kHz CD, 48 kHz DVD, and broadcast sample rates.
Technically the CS5330A-BSZ uses a multi-bit sigma-delta modulator followed by a digital decimation filter that combines the role of anti-alias filter and decimator. This integrated digital filtering achieves 0.05 dB passband ripple to 21.7 kHz and greater than 80 dB stopband rejection, eliminating the external analog anti-alias filter typically required by successive-approximation ADCs and simplifying the analog front-end to a simple passive RC network.
Typical applications include USB audio dongles, set-top box audio capture, automotive head-unit auxiliary and Bluetooth input stages, digital mixer consoles, AV receivers, and consumer karaoke systems. The wide 2-50 kHz sample-rate range also makes it suitable for broadcast and professional recording front ends where the same board must adapt to multiple standards.
When designing with this device, pay close attention to PCB layout: keep analog inputs short and symmetric, decouple VA and VD independently with 0.1 uF ceramic capacitors placed as close as possible to the pins, and isolate the digital ground return from the analog ground return to avoid coupling digital switching noise into the analog input path. A common-mode 0.1 uF capacitor at each analog input pin further improves PSRR.
This page consolidates distributor pricing, drop-in same-family alternatives, and PCB design notes not found in the manufacturer datasheet alone, giving the engineer a faster path from datasheet to production-ready stereo ADC front end.

典型应用
CS5330A-BSZ 适用于 7 应用s: USB Audio Dongle Front End, Set-Top Box Audio Capture, Automotive Head-Unit Auxiliary Input, Digital Mixer Console Input Channel, AV Receiver Stereo Input, Consumer Karaoke System Audio Capture, Professional Recording Front End.
USB Audio Dongle Front End
The CS5330A-BSZ is well matched to USB audio dongle designs where a compact, low-power stereo digitizer is needed in an 8-SOIC footprint. Its 94 dB dynamic range and 18-bit resolution are sufficient for 16-bit/44.1 kHz and 16-bit/48 kHz USB audio class 1 streams without compression. The integrated digital anti-alias filter eliminates an external op-amp stage, allowing the analog front end to be a simple AC-coupled RC network. Operating from a single +5 V USB-derived rail at 150 mW, it leaves ample power budget for the downstream USB codec and bus-powered design. The 2-50 kHz adjustable sample rate also lets one dongle support multiple sample-rate standards.
推荐
Set-Top Box Audio Capture
In set-top box audio capture paths the CS5330A-BSZ digitizes analog left/right audio from broadcast tuners or auxiliary inputs for downstream MPEG/audio encoding. Its 94 dB dynamic range preserves broadcast program material quality, while the linear-phase digital decimation filter maintains flat response across the audio band (0.05 dB to 21.7 kHz) without phase distortion that would alter timbre. Single +5 V operation simplifies the power tree, and the 8-SOIC footprint suits space-constrained mainboards. Variable 2-50 kHz sample rate lets the same hardware support NTSC/PAL broadcast rates (32 kHz, 48 kHz) and consumer recording rates (44.1 kHz).
推荐
Automotive Head-Unit Auxiliary Input
The CS5330A-BSZ suits automotive head-unit auxiliary and Bluetooth analog input stages where -40 C to +85 C industrial temperature range and 18-bit resolution are required. Its 94 dB dynamic range comfortably exceeds the perceived quality needs of in-cabin audio, and the integrated anti-alias filter reduces BOM count in cost-sensitive automotive designs. Single +5 V operation matches typical infotainment rails, while the small 8-SOIC package drops directly onto existing audio PCB land patterns. Wide 2-50 kHz sample-rate support accommodates hands-free, voice-prompt, and full-bandwidth audio capture on the same hardware.
推荐
Digital Mixer Console Input Channel
In digital mixer consoles, the CS5330A-BSZ provides per-channel stereo analog-to-digital conversion in a compact 8-SOIC footprint, allowing dense PCB layouts with many input strips. The 94 dB dynamic range captures live mixing dynamics, and the integrated digital anti-alias filter removes the external op-amp and active filter that would otherwise consume board area and add noise. The linear-phase decimation filter preserves transient attack in percussive sources. Variable sample-rate support lets the same console board adapt between 48 kHz studio and 96 kHz production environments when paired with a suitable dual-rate clock source.
推荐
AV Receiver Stereo Input
The CS5330A-BSZ serves AV receiver auxiliary stereo inputs where multiple analog sources must be digitized for surround processing. Its 94 dB dynamic range is sufficient for legacy analog sources (CD players, cassette decks, FM tuners), and the integrated digital filter eliminates external anti-alias hardware per channel. Single +5 V operation matches the receiver standby/auxiliary rail, simplifying power sequencing. The 8-SOIC footprint allows placement close to each RCA input jack, minimizing analog trace length. Adjustable 2-50 kHz sample rate supports global broadcast standards from 32 kHz to 48 kHz.
推荐
Consumer Karaoke System Audio Capture
Consumer karaoke systems use the CS5330A-BSZ to digitize stereo microphone and music-source inputs at 18-bit/44.1 kHz or 48 kHz for digital mixing and effects processing. Its 94 dB dynamic range accommodates both quiet vocal passages and loud music peaks without compression artifacts, while the integrated digital anti-alias filter keeps the analog front end simple. Single +5 V operation from a wall-adapter supply is supported, and the 8-SOIC surface-mount package fits compact karaoke-mixer PCBs. Industrial -40 C to +85 C screening ensures reliable operation in enclosed consumer electronics enclosures.
推荐
Professional Recording Front End
In multi-channel professional recording front ends, the CS5330A-BSZ provides a low-cost per-channel stereo ADC where many channels must be digitized on the same PCB. Its 94 dB dynamic range suits budget multi-track recorders, and the linear-phase digital decimation filter preserves transients critical for percussive recording. The 8-SOIC package supports dense channel layouts, while single +5 V operation simplifies rack-mount power design. The 2-50 kHz continuously adjustable sample rate lets one front-end card support 44.1 kHz CD mastering, 48 kHz video post, and 32 kHz broadcast applications through clock configuration alone.

设计说明
Place 0.1 uF ceramic decoupling capacitors as close as possible to both VA (pin 3) and VD (pin 5); add a 10 uF bulk tantalum or ceramic capacitor near each supply pin. Use a separate analog ground pour tied to AGND (pin 4) and route digital returns to DGND (pin 6), joining the two grounds at a single point near the IC to avoid digital switching currents coupling into the analog input path.
Keep analog input traces (AINL, AINR) short, length-matched, and routed away from the serial data output (SDOUT) and LRCK clock traces. Add a 0.1 uF AC-coupling capacitor in series with each analog input, and consider a common-mode 100 nF capacitor between each input pin and AGND to improve high-frequency PSRR. Series input resistors (typically 100 ohm-1 kohm) isolate the modulator from upstream op-amp stages.
Do not apply signals to AINL or AINR before VA and VD are powered up, as this can latch-up the input ESD structures. Ensure LRCK is present before data is read out, or SDOUT will be undefined. The CS5330A-BSZ is rated for +5 V single supply only; do not apply 3.3 V digital I/O directly to SDOUT/LRCK without a level shifter. Verify the master clock (MCLK) frequency matches the desired output sample rate per the datasheet's clock-mode table.
