CS5335-KS - 20-Bit Stereo Audio ADC | Cirrus Logic
MPN： CS5335-KS ✓ 啟用中CS5335-KS 概覽
An audio ADC is a specialized data-conversion IC that converts continuous left- and right-channel analog audio signals into discrete digital words for processing, storage, transmission, or playback. In the component hierarchy, the CS5335-KS is an ADC, a data converter, and an interface IC used in digital audio equipment. Its 20-bit conversion resolution preserves a substantial amount of amplitude detail, while its stereo architecture supports simultaneous or paired-channel digital audio acquisition.
The key verified features of the CS5335-KS are 20-bit resolution, two analog input channels, a 2 kHz-to-50 kHz signal bandwidth, one +5 V supply, and serial output for both channels. These characteristics make the converter suitable for consumer and professional audio systems that require more precision than a conventional 8-bit or 16-bit audio converter. The SSOP package also supports compact, surface-mounted circuit-board implementations.
The CS5335 performs analog-to-digital conversion as part of a signal chain that also includes anti-alias filtering. This integrated filtering helps remove higher-frequency content before the sampled data is converted into its digital representation. The available verified data does not state the internal converter architecture, clocking requirements, dynamic range, total harmonic distortion, input impedance, or output logic format, so those characteristics should be confirmed in the manufacturer datasheet before a precision audio design is released.
Typical uses include digital audio mixers, stereo playback and recording equipment, consumer audio appliances, sound-card signal paths, and industrial monitoring systems with audio inputs. In each case, the converter can sit after analog input conditioning and provide serial digital channel data to a DSP, codec, microcontroller, or storage interface. The available sources identify the CS5335 as a stereo converter for digital audio rather than as a general-purpose instrumentation ADC.
The primary design consideration is verification of the electrical interface. Designers should obtain the CS5335 pinout, confirm the analog input and output pin assignments, determine the required master clock and data-format settings, and calculate decoupling and layout requirements from the manufacturer datasheet. The verified web results identify the 20-SSOP package but do not provide a complete public pin table, so the pinout is not reproduced here to avoid inaccurate connections.
This page combines verified distributor specifications, package and channel details, pricing, source links, selection guidance, and application-specific engineering notes. It also distinguishes the documented CS5335-KS characteristics from parameters that remain unavailable, helping engineers identify what can be confirmed immediately and what must be checked in the official data.

典型應用
CS5335-KS 適用於 6 應用s: Digital Audio Mixer Signal Path, Stereo Playback and Recording Equipment, Consumer Audio Appliance, Sound Card and Audio Capture, Industrial Audio Monitoring, Digital Audio Test and Measurement.
Digital Audio Mixer Signal Path
The CS5335-KS fits a stereo mixer input stage because it converts two analog audio channels into 20-bit serial data while operating from a single +5 V supply. Its verified 2 kHz-to-50 kHz bandwidth covers the stated audio-band conversion range, and the integrated anti-alias filtering is useful when the converter follows the mixer’s gain and routing circuitry. The converter can feed a DSP or digital audio controller rather than performing mixing itself. Because the verified sources do not disclose input impedance, clock limits, or output timing, the analog front end and sample-rate plan must be checked against the manufacturer datasheet before release.
推薦
Stereo Playback and Recording Equipment
CS5335-KS is appropriate for equipment that must acquire left and right analog audio channels and present them to a digital subsystem. Its 20-bit resolution, two-channel architecture, and serial output suit digital audio conversion, while the integrated anti-alias filter helps condition the signal before conversion. In a playback-control product, the converter may support monitoring, loopback, or source capture rather than final loudspeaker drive. The verified data does not identify dynamic range or distortion, so a low-level signal design must not assume performance beyond the published 20-bit and 2 kHz-to-50 kHz bandwidth specifications.
推薦
Consumer Audio Appliance
A compact consumer audio appliance can use CS5335-KS to turn a pair of analog source signals into serial digital channel data. Its 20-pin SSOP package supports surface-mount assembly, while the single +5 V supply simplifies integration with digital audio subsystems. The converter is suitable when the design requires more resolution than a basic 8-bit or 16-bit audio input and only two channels are needed. Clock generation, analog input conditioning, and power decoupling must be designed from the official data because those implementation values are not present in the verified search excerpts.
推薦
Sound Card and Audio Capture
CS5335-KS can form the conversion front end of a two-channel sound card or line-level capture module. Its serial left- and right-channel output can pass digitized audio to a DSP, USB interface, or memory controller, while anti-alias filtering helps reject out-of-band energy before conversion. The 2 kHz-to-50 kHz verified bandwidth defines the signal range that should be considered during analog filtering. Designers still need to establish supported sampling rates, clocking, input impedance, and serial timing from the manufacturer datasheet before selecting the surrounding amplifier and interface components.
推薦
Industrial Audio Monitoring
CS5335-KS can support a stereo industrial monitoring subsystem that requires digital audio capture from two analog inputs. A conditioner can protect and scale the sensor or line-level signals, after which the converter supplies 20-bit serial data to a processor for storage, event analysis, or network transfer. The verified 2 kHz-to-50 kHz bandwidth is relevant when defining the accepted monitor signal band, and integrated anti-alias filtering supports conversion-stage frequency planning. Industrial temperature, transient protection, grounding, and EMC requirements are not documented in the supplied data and must be verified separately.
推薦
Digital Audio Test and Measurement
For a compact audio measurement instrument, CS5335-KS can convert two analog channels to serial digital data for analysis by a controller or DSP. Its 20-bit format and verified 2 kHz-to-50 kHz bandwidth make it relevant to audio-frequency acquisition, subject to confirming the actual sampling-rate capability and dynamic performance in the official data. Instrument designs should pay particular attention to analog reference noise, grounding, clock jitter, and calibration because those parameters are not supplied by the verified listings. The selected downstream processor must support the converter’s serial format and required clock arrangement.

設計說明
Confirm the complete 20-pin SSOP assignment from the official CS5335-KS data before routing the board. The verified sources confirm the package and state that CS5334 and CS5335 are pin-compatible, but they do not provide the individual pin names. Place the converter close to the analog input conditioning and supply-decoupling network, preserve a continuous ground reference for both channels, and keep digital clock and serial-output routing away from sensitive input traces. Do not finalize the footprint or pin mapping from the package name alone.
The integrated anti-alias filter does not remove the need for an appropriate analog input network. Establish the intended source impedance and maximum supported sampling rate from the manufacturer data, then design the channel filters for the verified 2 kHz-to-50 kHz signal bandwidth. Use matched routing for left and right where channel performance matters, and terminate the serial interface according to the documented clock and data-edge requirements. The supplied data does not expose dynamic range, jitter sensitivity, or output timing, so those values cannot be used for final impedance calculations.
Build the single +5 V supply network around the decoupling and sequencing recommendations in the official datasheet. Because the verified excerpts provide no input-voltage tolerance, quiescent-current, or reference-voltage specification, do not select the surrounding capacitors or estimate supply headroom from an assumed regulator tolerance. Verify power startup behavior, clock availability, and the required relationship between analog and digital supply sequencing. A stable +5 V rail is necessary but does not by itself establish the converter’s achievable audio performance.
Avoid selecting a generic ADC or codec solely because it also offers stereo inputs and serial output. The CS5335-KS is specifically documented as a pin-compatible 20-bit, two-channel, single +5 V digital-audio converter, and the only documented substitute family member in the supplied data is CS5334. Before changing either the converter or system clock, compare the official data for pin functions, sampling rate, dynamic range, distortion, master-clock requirements, output format, operating temperature, and lifecycle status. Generic search-tool results do not establish drop-in equivalence.
