PCM1723E
PCM1723E - 24-Bit 96kHz Stereo DAC | Texas Instruments
The Texas Instruments PCM1723E is a 24-bit stereo audio digital-to-analog converter with a 96 kHz maximum sampling rate, integrated phase-locked loop, digital interpolation filter, and analog output amplifier in a 24-pin SSOP package. It accepts 16-, 20-, or 24-bit input data in normal or I2S formats and supports sampling rates from 16 kHz through 96 kHz. The integrated PLL derives either 256fS or 384fS system clock from an external 27 MHz reference frequency.
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.
