CS5334-KS - 20-Bit Stereo Audio ADC | Cirrus Logic
MPN： CS5334-KS ✗ 停產CS5334-KS 概覽
An ADC is an analog-to-digital converter, a semiconductor that samples continuous analog voltage signals and represents them as numeric data. The CS5334 belongs to the ADC and DAC > ADC/DAC category, within the broader integrated-circuit and signal-conversion hierarchy. Its stereo architecture processes left and right audio channels simultaneously, while its integrated anti-alias filtering helps reject unwanted high-frequency energy before conversion.
The main characteristics of the CS5334-KS include 20-bit stereo conversion, a 2 kHz to 50 kHz input sampling range, a single +5 V supply, serial output, and a 20-SSOP package. According to the Cirrus Logic CS5334 family datasheet, the CS5334 and CS5335 are pin-compatible two-channel converters for digital audio systems. The same source states that both devices perform sampling, analog-to-digital conversion, and anti-alias filtering, generating 20-bit values for the left and right inputs in serial form at up to 50 kHz per channel.
The CS5334 is positioned as an audio-focused ADC rather than a general-purpose instrumentation converter. Its dedicated stereo signal path supports audio systems that require synchronized left and right channels and a serial interface suitable for connection to a digital audio processor. The supplied verified data does not state the exact output interface, clock architecture, converter SNR, THD, input impedance, or absolute digital output codes, so those details should be confirmed in the manufacturer datasheet before final circuit sign-off.
Typical uses include professional and consumer digital audio equipment, stereo recording interfaces, multimedia sound cards, digital mixing consoles, and embedded audio capture systems. In each case, the CS5334 can serve as the front-end converter that accepts left and right analog audio inputs and supplies serial 20-bit samples to a digital signal processor, audio codec, or controller. System designers should account for the +5 V analog supply, external clocking, input conditioning, reference requirements, and suitable PCB grounding when implementing the device.
A key design consideration is that CS5334-KS is an older, likely constrained-market component, so supply planning and functional verification deserve attention before committing to a production run. This page synthesizes the verified distributor and manufacturer-family information, documented alternatives, and application guidance to support initial component selection without inventing unavailable electrical details.

典型應用
CS5334-KS 適用於 6 應用s: Stereo Digital Audio Capture, Professional Audio Mixing Console, Multimedia Sound Card, Digital Recording Interface, Consumer Audio Equipment, Embedded Audio Sensor System.
Stereo Digital Audio Capture
The CS5334-KS fits stereo capture front ends because it converts two analog channels to 20-bit digital audio values and supports output word rates up to 50 kHz per channel. Place the converter after balanced or unbalanced input conditioning, then route its serial data to a digital audio processor or controller. Its integrated anti-alias filtering reduces unwanted high-frequency energy before conversion. The design should verify input full-scale range, clocking, and serial timing against the complete manufacturer datasheet.
推薦
Professional Audio Mixing Console
A mixing console can use the CS5334-KS for stereo input conversion where 20-bit resolution and independent left and right channels are useful. The converter produces serial data at up to 50 kHz per channel, allowing several synchronized conversion stages to feed a common digital mixing architecture. Integrated anti-alias filtering supports the audio frontend, while the single +5 V supply simplifies rail planning. Exact clock distribution, converter latency, and grounding must be validated during prototype verification.
推薦
Multimedia Sound Card
The CS5334-KS is applicable to a stereo multimedia sound card that requires conversion of left and right analog inputs into serial 20-bit samples. Its 2 kHz to 50 kHz input range covers the documented audio-oriented operating region, while integrated anti-alias filtering helps control out-of-band content before conversion. A practical implementation should provide clean +5 V power, low-noise reference support required by the full datasheet, and careful separation between analog input routing and digital clock and data paths.
推薦
Digital Recording Interface
For a compact recording interface, the CS5334-KS can convert two analog audio inputs to 20-bit serial data at up to 50 kHz per channel. The dedicated stereo path simplifies left and right synchronization, while the anti-alias filter is integrated into the conversion function. Designers should use the manufacturer datasheet to establish supported input operating modes, master-clock requirements, and digital output timing, then validate noise and distortion against the application’s recording-quality target.
推薦
Consumer Audio Equipment
The CS5334-KS can serve in consumer audio equipment that needs a dedicated stereo analog-to-digital stage before digital processing, storage, or transmission. Its 20-bit conversion, single +5 V supply, integrated anti-alias filtering, and serial output are suited to compact stereo signal paths. Because the converter family has limited supply visibility, engineers should also assess lifecycle risk and verify channel coupling, input headroom, clock jitter tolerance, and system latency using the complete datasheet.
推薦
Embedded Audio Sensor System
The CS5334-KS can convert two conditioned analog outputs from microphones, sensors, or instrumentation into serial 20-bit digital audio data. Its stereo organization and anti-alias filtering are useful when left and right channels must be captured together, and its documented output word rate reaches 50 kHz per channel. The implementation must confirm whether the sampling bandwidth and clock configuration satisfy the signal bandwidth, with additional care taken to keep noisy digital switching away from the analog inputs.

設計說明
The CS5334-KS operates from a single +5 V supply, but the converter will still require clean analog and digital power distribution. Route the supply directly to the relevant pins with low-impedance decoupling, maintain a continuous return path, and isolate noisy switching nodes from the audio inputs. The supplied data does not specify permitted supply tolerance or decoupling values, so use the manufacturer datasheet rather than applying generic capacitor selections.
Keep the left and right analog traces short, symmetric, and away from serial clock and data lines. Use a quiet ground strategy that prevents converter return currents from sharing a noisy path with the analog input reference. Place input-conditioning components close to the corresponding pins and keep the layout symmetrical to limit channel-to-channel timing and gain differences. Exact pin locations and the required grounding topology must be confirmed from the full datasheet.
Do not assume that a converter with the same function and package is electrically interchangeable without checking clock mode, serial-output format, control levels, latency, and power sequencing. The CS5335 is explicitly identified as pin-compatible with the CS5334, but the supplied excerpt does not describe every mode difference. Prototype the alternative with the same master clock, data-capture equipment, and representative audio signals before releasing a substitution.
Clock quality is central to a serial 20-bit audio converter because timing jitter can degrade conversion performance. Use a clean, low-jitter clock source, avoid unnecessary stubs, and route clock and serial data with controlled return paths. Verify the complete interface with an oscilloscope or logic analyzer under the intended sample rate. The verified source states a maximum word rate of 50 kHz per channel but provides no detailed clock-frequency or timing limits.
