PCM56P 概要
What is a PCM56P? It is an audio DAC, a digital-to-analog converter, and a member of the broader signal-conversion and data-acquisition semiconductor hierarchy. In a signal chain, it receives serial digital audio data and produces an analog voltage through a current-switched resistor ladder and integrated output amplifier. Its self-contained architecture reduces the need for external reference and output-buffer components, while dual supplies support bipolar analog output requirements.
The key verified features include 16-bit resolution, 96 dB dynamic range, and internal stable low-noise Zener reference. The converter uses high-speed current switches and a fast-settling, low-noise output operational amplifier. It operates from positive and negative supplies ranging from ±5V to ±12V, and the manufacturer states that power dissipation with ±5V supplies is typically less than the value specified in the datasheet.
Its series-input architecture is appropriate for audio equipment requiring predictable digital-to-analog conversion, including CD-player DAC boards, digital audio instruments, high-end audio preamplifiers, and laboratory signal-conversion equipment. The ±5V to ±12V supply requirement is an important design constraint and should be checked against the analog output swing and downstream biasing requirements.
For implementation, follow the manufacturer datasheet for pin connections, serial-data timing, analog grounding, and supply decoupling. Do not substitute PCM56P with a different package or interface without verifying the complete pinout and electrical conditions. This page consolidates verified manufacturer information, distributor identification, and cross-reference results while marking unavailable technical values explicitly.

主な用途
PCM56P の用途: 6 件s: High-End Audio DAC Board, CD-Player Digital-to-Analog Conversion, Digital Audio Instrument, Precision Analog Signal Generation, High-End Preamplifier Signal Path, Audio Measurement and Monitoring.
High-End Audio DAC Board
The PCM56P fits a high-end audio DAC board because it combines 16-bit resolution with 96 dB dynamic range and a low-noise internal Zener reference in one monolithic converter. The serial input can receive digital audio data from a suitable transport or digital interface, while the integrated resistor ladder and output amplifier simplify the analog conversion stage. Designers should provide ±5V to ±12V supplies, correct bypass capacitance, and an output network selected for the intended load. The verified data does not specify a numeric settling time or output range, so those values must be checked in the manufacturer datasheet before setting the system bandwidth.
おすすめ
CD-Player Digital-to-Analog Conversion
PCM56P is well suited to a dedicated CD-player DAC board where a 16-bit serial digital stream must become a high-quality analog audio signal. Its monolithic architecture includes the voltage reference, current switches, resistor ladder, and output operational amplifier, reducing the number of separate precision analog components. The 96 dB dynamic-range specification supports high-fidelity audio designs, but the implementation must still account for clock timing, output filtering, grounding, and supply-noise coupling. Use the exact PCM56P suffix and manufacturer timing requirements to avoid interface mismatches.
おすすめ
Digital Audio Instrument
The PCM56P can be used in a digital audio instrument that needs a deterministic 16-bit serial DAC with a self-contained precision reference and output amplifier. Its ±5V to ±12V supply range provides flexibility for bipolar analog output arrangements, while the integrated architecture helps minimize board area and external-component count. The converter should be paired with a reconstruction or smoothing filter appropriate to the target bandwidth and output impedance. Because the supplied data does not state input clock limits or settling time, the complete signal path must be validated from the manufacturer documentation and measured prototypes.
おすすめ
Precision Analog Signal Generation
PCM56P is suitable for laboratory and test-equipment signal-generation prototypes that convert stored or externally supplied serial samples into an analog voltage. Its 16-bit resolution and 96 dB dynamic range provide a useful starting point for audio-band and general precision signal experiments. The monolithic converter simplifies the analog core, but a complete instrument still needs a clock source, sample-rate control, reconstruction filtering, level control, output protection, and calibration. Verify allowed input rates and output specifications in the datasheet before using the converter outside its intended audio envelope.
おすすめ
High-End Preamplifier Signal Path
In a high-end preamplifier or external DAC chassis, PCM56P can provide the conversion stage before a carefully selected analog output amplifier. The internal low-noise Zener reference and integrated output amplifier are useful when the design objective is a compact, self-contained DAC section rather than a discrete ladder and buffer. Supply rails, grounding, and output coupling must be arranged to preserve the converter’s intended bipolar operation. Avoid assuming that any amplifier can be connected directly; check output impedance, DC offset, clipping behavior, and the manufacturer’s recommended output network.
おすすめ
Audio Measurement and Monitoring
PCM56P can serve as the playback or signal-generation DAC in an audio monitoring system where a controlled digital source is needed for amplifier, transducer, or room testing. Its 16-bit resolution provides a defined conversion depth, and the 96 dB dynamic-range figure helps establish an appropriate noise and level budget. For repeatable measurements, the system should use known digital test patterns, calibrated output attenuation, and a defined reconstruction filter. The supplied data does not specify clock rate, output swing, or channel count, so those limits must be verified before setting test bandwidth.

設計ノート
Use separate positive and negative supplies within the manufacturer-supported ±5V to ±12V range, and place the required bypass capacitors close to the supply pins according to the official datasheet. The PCM56P is a dual-supply audio DAC, so the rails are not interchangeable with a single-supply 5V design without changing the biasing and output architecture. Confirm polarity and output common-mode behavior before energizing the board.
Keep the serial-data and clock traces short, provide a stable return path, and separate digital input routing from the analog output and supply nodes. Because the converter includes a precision reference, current switches, a resistor ladder, and an output amplifier, grounding and supply layout directly affect noise performance. Use the manufacturer’s recommended layout and component placement rather than treating the PDIP part as a generic digital IC.
Verify the serial interface timing against the official PCM56 family documentation and terminate or condition clock and data lines according to the source device. A mismatch in clock polarity, data setup time, or signal integrity can create conversion errors even when the DAC’s nominal resolution is 16 bits. For audio outputs, follow the manufacturer’s recommended reconstruction or smoothing network and measure the final bandwidth and distortion in the completed system.
Do not treat PCM56P and PCM56U as identical drop-in parts: PCM56P is identified as PDIP-16 and PCM56U as SOIC-16. Also do not assume every PCM56P-K, -L, or -J suffix has identical grade-specific limits or lifecycle status. Confirm the exact orderable MPN, package, pinout, supply conditions, and analog requirements before replacing a failed device.
