PCM1723E - 24-Bit 96kHz Stereo DAC | Texas Instruments
Référence : PCM1723E ✓ ActifPCM1723E Présentation
An audio DAC is a semiconductor that converts digital audio samples into analog voltage signals suitable for headphone, line, or power-amplifier inputs. In the signal-chain hierarchy, PCM1723E is a stereo DAC, which belongs to the broader digital-to-analog converter, audio converter IC, interface IC, and semiconductor categories. Its integrated PLL reduces the need for a separate clock-generation circuit when the system provides the required 27 MHz reference.
The PCM1723E accepts several native word lengths and multiple standard sampling rates, making it suitable for consumer audio equipment, computers, televisions, and digital audio systems. According to the supplied manufacturer and distributor information, it accepts 16-, 20-, or 24-bit data, supports 16, 22.05, 24, 32, 44.1, 48, 64, 88.2, and 96 kHz sampling rates, and provides a 94 dB dynamic-range figure in the available datasheet summary.
Internally, the converter uses a third-order Delta-Sigma modulator, a digital interpolation filter, and an analog output amplifier. This architecture converts the digital PCM stream into a pair of analog stereo outputs while the programmable PLL synchronizes the converter to an external reference. The PCM1723 family description also identifies 96 dB SNR for PCM1723E, providing a more useful system-level indication than bit depth alone.
Typical uses include DVD and CD player analog outputs, digital television audio, personal-computer multimedia systems, home-theater equipment, and other consumer electronics requiring two-channel audio playback. The 24-pin SSOP package also supports compact board layouts, although its lead pitch and thermal behavior must be considered during PCB assembly.
When designing around the PCM1723E, provide the required external 27 MHz reference and route it cleanly to the device. Confirm that the audio master clock, serial data, and I2S or normal-format timing meet the selected sample-rate requirements. Decoupling and analog-output grounding should follow the layout guidance in the manufacturer datasheet to preserve converter performance.
This product record consolidates manufacturer specifications, distributor pricing, sourcing data, and verified family references into an engineer-focused comparison. It also distinguishes the directly evidenced PCM1723E/2K variant from speculative replacements, preventing a package-only assumption from being presented as guaranteed pin compatibility.

Applications typiques
PCM1723E convient pour 6 applications: Home-Theater Stereo Audio, Digital Television Audio Output, Computer Multimedia Audio, CD and DVD Player Outputs, Portable Audio Equipment, Consumer Audio System.
Home-Theater Stereo Audio
The PCM1723E fits two-channel home-theater output stages that require normal-format or I2S audio and standard consumer sampling rates. Its 24-bit input capability accepts 16-, 20-, or 24-bit streams, while the supported range extends from 16 kHz through 96 kHz. The integrated third-order Delta-Sigma modulator, interpolation filter, output amplifier, and PLL provide a consolidated conversion path. According to the Texas Instruments product-page summary, the programmable PLL derives a 256fS or 384fS system clock from an external 27 MHz reference, reducing the number of separate clocking blocks. The design must still provide clean reference routing, suitable decoupling, and analog-output return paths, with final component values selected from the manufacturer datasheet.

Digital Television Audio Output
PCM1723E can provide the stereo DAC stage for a digital television or display design that receives PCM audio and drives an analog amplifier. Its support for 16-, 20-, and 24-bit input, together with sampling rates from 16 kHz to 96 kHz, covers common digital-audio streams used in consumer video equipment. The converter integrates the Delta-Sigma modulator, digital interpolation filter, and analog output amplifier, while its PLL accepts a 27 MHz reference and produces a 256fS or 384fS system clock. In practice, the television design should isolate the analog outputs from display-related switching noise and verify the required audio format and clock relationships directly against the manufacturer timing guidance.
Recommandé
Computer Multimedia Audio
The PCM1723E is suitable for computer and multimedia equipment requiring a compact stereo analog-output path from a digital audio source. It accepts I2S or normal-format data at word lengths of 16, 20, or 24 bits, making it adaptable to source-device formats, and supports sample rates up to 96 kHz. Its integrated programmable PLL and analog output amplifier reduce the number of external functional blocks needed for a basic playback design. According to the manufacturer summary, the PCM1723 includes a third-order Delta-Sigma modulator and digital interpolation filter. Designers should verify the host interface timing, isolate noisy computer and display supplies, and implement the analog output network specified by Texas Instruments rather than selecting capacitors from generic guidance.
Recommandé
CD and DVD Player Outputs
PCM1723E aligns with CD and DVD player designs requiring a two-channel DAC capable of 44.1 kHz and 48 kHz playback as well as higher-rate media formats. The converter supports 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz, along with 16-, 20-, and 24-bit input data. Its integrated PLL can derive the required 256fS or 384fS processing clock from an external 27 MHz reference. The manufacturer-described third-order Delta-Sigma architecture and interpolation filter provide the digital conversion core, while the integrated output amplifier supports a more compact analog path. Final selection requires checking the player’s electrical format, output level, load, and all datasheet-recommended passive networks.
Recommandé
Portable Audio Equipment
PCM1723E can serve as the digital-to-analog conversion element in portable or compact audio equipment where two analog stereo channels and 96 kHz playback are required. Its 24-pin SSOP package supports space-conscious layouts, while the integrated PLL, digital interpolation filter, and analog output amplifier reduce external component count. According to the supplied manufacturer information, the converter accepts 16-, 20-, or 24-bit input and normal or I2S formats. Portable-product designs still need a careful battery-versus-output-voltage plan, because the supplied data does not state the analog or digital supply ranges. Confirm those limits, output impedance, and thermal performance in the manufacturer datasheet before selecting the device for a battery-powered implementation.
Recommandé
Consumer Audio System
The PCM1723E is appropriate for compact consumer audio products that convert digital stereo sources into analog line-level signals. It supports the common 44.1 kHz and 48 kHz rates as well as 16, 22.05, 24, 32, 64, 88.2, and 96 kHz, while accepting 16-, 20-, or 24-bit words. The integrated PLL, third-order Delta-Sigma modulator, digital interpolation filter, and analog output amplifier provide the core conversion functions described by Texas Instruments. For a complete product, the digital source must provide the expected normal or I2S stream and the board must include the specified bypass and output networks. Since the supplied source lists 96 dB SNR and 94 dB dynamic range, system documentation should retain those as separate performance statements.

Notes de conception
Route the 27 MHz reference to the PCM1723E with a short path and stable return reference, and keep the clock away from the stereo analog outputs. Place the required bypass capacitors adjacent to their associated supply pins using the manufacturer pin assignments and application diagram. Confirm package orientation, pin numbering, and copper clearances against the official 24-pin SSOP drawing before fabrication.
Verify normal-format or I2S framing, bit-clock and word-clock ratios, and the relationship between the 27 MHz reference and the 256fS or 384fS PLL output before releasing the PCB. The digital audio traces should be routed over a continuous reference plane, with media transitions minimized and analog outputs isolated from switching nodes. These checks prevent data-interface timing errors that can appear as intermittent noise or channel misalignment.
Do not infer PCM1723E supply-voltage limits, output impedance, or a complete replacement pinout from the supplied distributor summaries. Those values are marked as data needed. Before schematic or layout release, consult the current Texas Instruments PCM1723 datasheet and ordering information, and confirm that any selected alternative matches power pins, clock behavior, control logic, and analog output connections.
