PCM1606E - 24-Bit 6-Ch Audio DAC | Texas Instruments
N.º da peça: PCM1606E ✓ AtivoPCM1606E Visão geral
A digital-to-analog converter, or DAC, converts digital audio samples into corresponding analog voltage signals. The PCM1606E belongs to the delta-sigma DAC family within the broader mixed-signal IC and audio converter hierarchy. Its six-channel architecture supports simultaneous or multiplexed reproduction of multiple audio channels, while the enhanced multilevel delta-sigma architecture reduces quantization-related distortion compared with a basic single-bit delta-sigma converter.
Key performance features include 24-bit resolution, 192 kHz sampling, 103 dB typical dynamic range, 103 dB typical SNR, and 0.004% typical THD+N. The converter uses 8-times oversampling interpolation and produces a typical full-scale output of 3.1 Vp-p. Its 4.5 V to 5.5 V supply range suits conventional 5 V audio equipment, while the I2S interface supports direct connection to suitable digital audio processors.
The PCM1606E is designed for multichannel audio conversion where six channels and high-resolution reproduction are required. Its 103 dB SNR and 0.004% THD+N are particularly relevant to preamplifiers, powered speakers, home-theater equipment, and professional audio products. The 20-pin SSOP package supports compact surface-mount assembly but requires careful analog and digital layout to preserve performance.
Typical applications include 5.1-channel home-theater DAC boards, multichannel preamplifiers, digital audio consoles, powered-speaker crossover boards, active speaker networks, and high-resolution audio playback equipment. An I2S source supplies the PCM stream, and the analog outputs provide six full-scale audio channels for subsequent amplification or line-level processing.
Designers should provide stable 5 V analog and digital supplies, place decoupling capacitors close to the supply pins, and follow the manufacturer datasheet layout for the analog output, clock, and I2S signals. The operating voltage must remain between 4.5 V and 5.5 V, while clocking and digital-interface timing should satisfy the published PCM1606E requirements.
This product page consolidates verified distributor specifications, sourcing information, application guidance, and the available pin-compatible alternative. It also distinguishes confirmed data from parameters that require validation against the manufacturer datasheet before a new PCB layout or production release is approved.

Aplicações típicas
PCM1606E é adequado para 6 aplicaçãos: 5.1-Channel Home-Theater DAC, Multichannel Audio Preamplifier, Powered-Speaker Converter Board, Professional Audio Playback, Digital Audio Source and Recording Review, High-Resolution Audio Player.
5.1-Channel Home-Theater DAC
The PCM1606E fits a 5.1-channel home-theater conversion stage because its six-channel architecture matches a typical surround-sound output count without requiring six separate converter packages. The 24-bit resolution and 192 kHz sampling support high-resolution source formats, while 103 dB typical SNR and 0.004% typical THD+N provide a clean starting point for amplifier inputs. Use an I2S-compatible processor, preserve the converter’s 4.5 V to 5.5 V supply requirement, and validate the board-level filtering before production release.
Recomendado
Multichannel Audio Preamplifier
PCM1606E is appropriate for a multichannel preamplifier that requires six simultaneous analog outputs and accepts digital audio from a source processor. Its 3.1 Vp-p typical full-scale output provides a defined conversion target, while 103 dB typical dynamic range and 103 dB typical SNR help preserve low-level audio information. The design should include appropriate output filtering, stable analog and digital supplies, and short return paths from the converter to the next gain stage.
Recomendado
Powered-Speaker Converter Board
The PCM1606E can serve as the digital-to-analog conversion element in a powered-speaker or active-speaker crossover board. Six channels allow separate digital streams for surround outputs or multiway speaker channels, and the 24-bit, 192 kHz converter supports high-resolution source material. Its 0.004% typical THD+N and 103 dB typical SNR are useful when preserving signal integrity before amplification. Clock jitter, grounding, and analog-output loading must be checked at the system level.
Recomendado
Professional Audio Playback
PCM1606E is suitable for professional playback equipment requiring high-resolution, multichannel digital-to-analog conversion. The enhanced multilevel delta-sigma architecture, 192 kHz sampling, 103 dB typical SNR, and 0.004% typical THD+N suit conversion tasks where channel consistency and low distortion are important. A professional implementation should validate clocking over operating temperature, maintain the specified supply range, and follow the manufacturer’s recommended analog and digital partitioning.
Recomendado
Digital Audio Source and Recording Review
PCM1606E can be used in a digital audio source or recording-review system to convert I2S streams into six analog channels for monitoring and evaluation. Its 24-bit resolution retains detailed digital sample representation, and the 192 kHz sampling capability supports high-rate source material. The 103 dB typical SNR provides useful headroom for comparing source quality, while the 3.1 Vp-p typical full-scale output simplifies signal-level planning. A calibrated capture system is required for meaningful comparative measurements.
Recomendado
High-Resolution Audio Player
PCM1606E fits a high-resolution multi-zone audio player when the design needs six analog output channels from an I2S source. Its 192 kHz sampling rate, 103 dB typical dynamic range, and 103 dB typical SNR support detailed music reproduction, while 8-times oversampling interpolation is integrated into the conversion stage. The converter should receive a low-jitter clock and clean supplies. Analog output filtering and channel-level calibration remain important when moving from evaluation boards to a finished player.

Notas de projeto
The PCM1606E requires a supply between 4.5 V and 5.5 V. Place the required bypass capacitors immediately beside the supply and ground pins and keep analog and digital return currents separated as far as practical. Verify ripple and startup behavior on the assembled board because converter performance can be affected by supply noise even when the nominal 5 V level is correct.
Follow the manufacturer datasheet layout for the 20-SSOP device rather than inferring pin assignments from a third-party package drawing. Keep the I2S and clock traces away from the analog outputs, provide a continuous ground reference, and place output-filter components close to their corresponding pins. A short, symmetric analog output path helps reduce channel-to-channel timing and routing differences.
Do not treat the PCM1681PWP as an automatic substitute without reviewing its clock, filtering, output-loading, and supply requirements. The supplied cross-reference data confirms the same 20-SSOP footprint and pinout for most 5 V I2S applications, but it does not provide a complete parameter table. Validate the substitution against the manufacturer datasheet and the target board’s test limits.
Treat the I2S data, bit clock, and master clock as a coordinated timing group. Use short, continuous routes with a nearby ground reference and avoid test pads or long stubs unless their effects are characterized. Since the verified specification is 192 kHz sampling, confirm that the source, clock generator, and digital transport meet the converter’s timing requirements at the highest intended rate.
Informações de conformidade
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
