SI3000-KS Descripción general
A voice-band codec is an audio interface integrated circuit that converts analog microphone or line-level signals into digital PCM data and converts digital audio back into an analog output. In the broader device hierarchy, the SI3000-KS belongs to audio codecs, interface ICs, signal-conversion devices, and semiconductor components. Its one-ADC and one-DAC architecture is suitable for compact telephony, communications, embedded voice, and audio-assistance designs where a dedicated low-bandwidth audio path is required. The 4 kHz to 12 kHz sample-rate range targets narrow voice bandwidth rather than full-spectrum hi-fi audio.
The main engineering benefits are the stated 84 dB conversion dynamic range, integrated microphone and speaker-drive support, and programmable analog gain controls. Input gain or attenuation helps match microphone levels to the converter, while output gain or attenuation helps condition the playback signal before the speaker amplifier. The 30 dB microphone preamplifier provides additional headroom for weak microphone sources. Because the verified data does not provide supply voltage, clock requirements, control-interface details, absolute maximum ratings, or thermal data, those values must be obtained from the manufacturer datasheet before final schematic or PCB approval.
Use the SI3000-KS when the design specifically needs a narrowband voice codec with integrated ADC, DAC, microphone preamplification, and programmable gain. Suitable application directions include telephone handsets, intercom systems, industrial voice terminals, automotive voice interfaces, and embedded communication modules. The automotive positioning appears in distributor descriptions, but qualification status and exact environmental requirements are not independently established by the supplied data and therefore remain unknown. A design must also verify that the required sample rate, serial interface, audio levels, power rails, and external components match the device datasheet.
The principal design consideration is lifecycle risk. Mouser states “Leaded - Not recommended for new designs, see Si3000-C-FS datasheet,” while DigiKey lists SI3000-KS for purchase. Engineers should therefore treat the SI3000-KS as a potentially legacy or transition-related device and compare it with the recommended current family before committing a new design. The exact pinout is not reproduced in the supplied verified snippets, so pin-level wiring must be confirmed from the official manufacturer datasheet. This page combines the verified distributor classification and specifications with procurement context and design guidance without inventing missing electrical parameters.
This page synthesizes distributor listings, lifecycle notices, codec specifications, replacement guidance, and practical application considerations. It distinguishes verified facts from unavailable parameters, highlights the Skyworks recommendation concerning Si3000-C-FS, and avoids treating a distributor availability statement as proof of long-term design support.

Aplicaciones típicas
SI3000-KS es adecuado para 6 aplicacións: Telephony Voice Terminals, Automotive Voice Interfaces, Industrial Intercom Systems, Two-Way Communication Modules, Voice-Controlled Embedded Products, Hands-Free Voice Communication.
Telephony Voice Terminals
The SI3000-KS fits telephony voice terminals that require one analog microphone input and one analog voice output in a compact 16-pin SOIC. Its verified 84 dB ADC and DAC dynamic range provide a defined conversion performance for narrowband speech, while the 30 dB microphone preamplifier and programmable input gain or attenuation help condition weak microphone signals. The 4 kHz to 12 kHz sample-rate range is appropriate for speech-band systems rather than music reproduction. In a new design, lifecycle status and the Si3000-C-FS transition should be reviewed before production commitment.
Recomendado
Automotive Voice Interfaces
The SI3000-KS is identified by distributor data as an automotive voiceband audio codec, making it relevant to existing vehicle voice and communication designs. Its one-ADC and one-DAC channels support a microphone-to-digital-audio and digital-audio-to-analog-audio signal path, while the 30 dB microphone preamplifier supports low-level microphone input conditioning. The verified data does not state AEC-Q100 qualification, automotive temperature limits, or production qualification, so those items must be confirmed with Skyworks. Use it for an existing qualified platform rather than assuming automatic new-design approval.
Recomendado
Industrial Intercom Systems
The SI3000-KS is suitable for industrial intercom and station equipment requiring narrowband speech conversion in a small package. The 4 kHz to 12 kHz sample-rate range aligns with voice-band capture and playback, while programmable input and output gain or attenuation provide level adjustment between a microphone source and the codec’s analog signal path. The 16-pin SOIC package can simplify board layout compared with discrete ADC and DAC implementations. Before deployment, verify supply voltage, clocking, digital interface, electrical noise performance, and the current Skyworks lifecycle statement in the manufacturer documentation.
Recomendado
Two-Way Communication Modules
The SI3000-KS can serve as the audio conversion element in two-way embedded communication modules because it combines one ADC and one DAC in one codec. The microphone preamplifier and programmable gain controls support transmit-side level conditioning, while programmable output gain or attenuation supports receive-side adjustment before an external amplifier or speaker driver. Its voice-band 4 kHz to 12 kHz sample-rate capability is appropriate for speech rather than full audio. The supplied data does not identify the digital serial protocol, so the host processor interface must be established from the authoritative datasheet.
Recomendado
Voice-Controlled Embedded Products
The SI3000-KS can support embedded voice-capture and playback functions where a dedicated low-bandwidth codec is preferable to a general-purpose high-resolution audio converter. Its 84 dB ADC and DAC dynamic-range figures, integrated microphone preamplifier, and programmable gain controls cover the core analog conversion functions. The 16-pin SOIC format is practical for compact controller boards with external microphones and audio amplifiers. The exact power rails, sample-clock requirements, digital interface, and output-drive limits are not present in the verified snippets and must not be inferred.
Recomendado
Hands-Free Voice Communication
The SI3000-KS is relevant to hands-free voice communication products because it provides a microphone input path, a DAC output path, analog level adjustment, and a voice-band sample-rate range. The 30 dB microphone preamplifier is useful when the microphone produces a small signal, while output gain or attenuation can help match the codec output to a downstream amplifier. It is not a complete power amplifier, and the supplied data does not specify speaker-drive power or load capability. Confirm those details and the device’s lifecycle status in the current Skyworks documentation.

Notas de diseño
Do not treat the SI3000-KS as an unqualified new-design choice without reviewing the lifecycle notice. Mouser explicitly describes it as leaded and not recommended for new designs, pointing users to the Si3000-C-FS datasheet. For an existing design, preserve the original pinout and verify the manufacturer document before substitutions. For a new design, compare the current family, confirm supply and lifecycle status, and obtain written supplier availability as of 2026-10-23.
Verify the codec supply voltage, analog input range, digital interface voltage, and external microphone or amplifier levels from the authoritative datasheet before connecting any signal. The supplied snippets confirm a 30 dB microphone preamplifier and programmable input and output gain or attenuation, but they do not provide supply limits or absolute maximum ratings. Incorrect gain, biasing, or signal amplitude can cause clipping and excessive power even when the nominal voice-band sample rate is correct.
Keep analog microphone and codec connections short, isolate them from switching supplies and digital clocks, and place required bypass and interface components according to the manufacturer reference layout. The 16-pin SOIC package is identified, but individual pin functions and recommended land pattern details are not included in the supplied data. Do not reconstruct a footprint or pinout from the package name alone; verify the official drawing and pin table before PCB release.
Información de cumplimiento
The supplied verified snippets identify automotive voiceband application but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-mineral declarations. Compliance must be confirmed with the current Skyworks manufacturer documentation.
