PCM1808PWR Übersicht
An audio ADC is a data-acquisition IC that transforms continuous analog voltage signals into digital codes for storage, processing, transmission, or playback. The PCM1808 belongs to the broader delta-sigma ADC family, within ADCs, data converters, and signal-chain semiconductors. Its stereo architecture supports two single-ended inputs rather than balanced differential channels, making it suitable for compact consumer and embedded audio equipment.
Key verified features include 24-bit resolution, a maximum sampling rate of 96 kHz, 99-dB signal-to-noise ratio, 64-times oversampling, and an integrated digital decimation filter. The manufacturer describes support for both master and slave operating modes. These features allow the converter to capture audio-band signals while reducing analog front-end requirements and limiting out-of-band energy before digital processing.
The PCM1808 uses a delta-sigma modulator architecture, with the decimation filter and high-pass filter implemented on-chip. The 99-dB SNR specification indicates a favorable noise floor for high-resolution audio capture, while the 24-bit word length preserves fine amplitude detail. The supplied distributor record identifies the device as a serial, single-ended-input, stereo audio ADC in a 14-TSSOP package.
Typical applications include digital audio recording, multimedia input stages, USB or embedded audio interfaces, consumer audio equipment, and systems requiring stereo analog-to-digital conversion. In a signal chain, an analog preamplifier drives the PCM1808 inputs, and the resulting digital stream is routed to a processor, codec interface, or storage subsystem. The converter is especially appropriate where two single-ended channels and a compact surface-mount package are preferred.
Designers should verify the complete electrical interface, pin names, clocking requirements, and supported operating conditions against the official PCM1808 datasheet before layout. The TSSOP footprint requires careful analog trace routing and decoupling. Because the verified source provides no exact pinout table or detailed application-specific companion parts, those values are intentionally not invented here. This page consolidates verified manufacturer and distributor information while clearly separating unavailable parameters.

Typische Anwendungen
PCM1808PWR ist geeignet für 6 Anwendungs: Stereo Digital Audio Recording, Embedded Multimedia Audio Input, USB Audio Interface, Consumer Audio Equipment, Audio Test and Measurement, Digital Audio Playback and Transmission.
Stereo Digital Audio Recording
PCM1808PWR fits stereo recording front ends that need two single-ended analog channels converted into 24-bit digital audio at up to 96 kHz. Its verified 99-dB SNR provides a useful starting point for selecting a low-noise signal chain, while the integrated high-pass filter removes DC offset from the input. Place a suitable analog preamplifier ahead of the ADC, terminate the inputs according to the datasheet, and route the digital output to the recorder, DSP, or storage controller. The converter is appropriate when the system accepts single-ended inputs and does not require balanced-input capability.
Empfohlen
Embedded Multimedia Audio Input
PCM1808PWR can serve as the analog-to-digital front end in embedded multimedia equipment requiring compact stereo audio capture. The 14-pin TSSOP package and single-ended input architecture suit board designs that need two channels without balanced-input routing. Its 24-bit word length supports downstream gain adjustment and signal processing, while the 96-kHz maximum sampling rate covers high-resolution audio use cases. The system designer must provide suitable clocking, digital-interface compatibility, decoupling, and analog input conditioning before connecting the converter to an embedded processor.
Empfohlen
USB Audio Interface
PCM1808PWR is applicable to USB audio interfaces where two analog inputs must become a high-resolution digital stream. The converter's 24-bit resolution and 99-dB SNR align with audio interfaces that preserve dynamic range before downstream volume control and encoding. Use an appropriate low-noise analog preamp and antialias network, then connect the ADC digital interface to the USB audio controller. The verified source does not identify a specific USB controller or reference design, so system-specific clocking, format, and latency requirements must be validated independently.
Empfohlen
Consumer Audio Equipment
PCM1808PWR can be used in consumer audio equipment that captures stereo line-level or microphone-conditioned signals. Its single-ended inputs simplify board planning compared with a balanced-input converter, provided the analog source impedance and signal amplitude are within the device's verified operating limits. The 96-kHz sampling capability and 24-bit conversion provide a strong basis for high-resolution playback and recording products. The integrated high-pass filter helps reject DC offset, but correct input biasing and analog grounding remain essential for low distortion and reliable operation.
Empfohlen
Audio Test and Measurement
PCM1808PWR is suitable for audio test equipment when the measurement chain requires simultaneous stereo conversion and a documented 24-bit, 96-kHz capability. The 99-dB SNR specification can help establish the converter's nominal noise contribution, although the complete measurement depends on the source impedance, analog gain, clock quality, and PCB layout. Keep analog and digital return paths separated, use a quiet reference source, and calibrate the measurement path after installation. These practices make the converter's digital output more useful for repeatable audio analysis.
Empfohlen
Digital Audio Playback and Transmission
PCM1808PWR can serve as the capture-side ADC in equipment that records, transmits, or processes audio digitally. The device converts two single-ended channels and removes input DC through its integrated high-pass filter, reducing the need for a separate DC-blocking stage. Its delta-sigma architecture and 64-times oversampling are useful for audio-band digitization, while the digital decimation filter shapes the converted stream. Designers should verify the supported serial format and clocking directly from the official datasheet before selecting this converter for a particular transport standard.

- Integrated conversion filtering (vs. PCM1808PW)
- High-resolution audio conversion (vs. PCM1808PW)
Designhinweise
Keep the PCM1808 analog inputs, reference path, and associated decoupling in a compact, quiet section of the PCB. Route the two single-ended channels with matched geometry where practical, and keep digital clock and data traces away from sensitive analog nodes. Because the supplied verified data does not specify the complete pinout or layout values, use the manufacturer datasheet for exact placement and grounding guidance.
Design the PCM1808 supply, analog input biasing, and digital interface around the manufacturer's electrical limits before selecting passive values. The verified data identifies a stereo 24-bit ADC but does not provide the detailed supply-voltage range, input range, or pin-specific capacitor recommendations. Do not infer those values from generic ADC designs; follow the official PCM1808 datasheet and validate startup and shutdown behavior in the target system.
Treat the delta-sigma clock and digital interface as critical signal-integrity paths. Provide short, controlled connections, avoid unnecessary stubs, and confirm that the downstream controller supports the converter's verified serial interface and master/slave arrangement. The 64-times oversampling and integrated decimation filter help shape the digital result, but they do not compensate for poor clock routing, inadequate analog drive, or unstable source impedance.
Do not substitute PCM1808PWR solely because a distributor labels a similar PCM1808 suffix as equivalent. The verified comparison describes PCM1808PW as having identical primary performance profiles, but it also recommends checking manufacturer datasheets for minor package or material variations. Confirm the exact TSSOP footprint, pin assignment, electrical limits, clock interface, and sourcing status before approving a drop-in replacement.
