PCM1753DBQR

ADCs/DACs - Special Purpose Overview

The PCM1753DBQR is a stereo audio digital-to-analog converter (DAC) from Texas Instruments, utilizing an enhanced delta-sigma architecture with fourth-order noise shaping and eighth-order amplitude quantization. It supports sampling rates up to 192 kHz and offers 24-bit resolution. The device features a signal-to-noise ratio of 106 dB and total harmonic distortion plus noise of 0.002%. It operates on a single 5 V supply within a voltage range of 4.5 V to 5.5 V. The component is housed in a 16-pin SSOP package and includes a three-wire serial control interface for register access.

ADCs/DACs - Special Purpose Feature Summary

• Enhanced Delta-Sigma Architecture: Employs fourth-order noise shaping and eighth-order amplitude quantization for superior dynamic performance and clock jitter tolerance.
• High Fidelity Audio Performance: Delivers a typical SNR of 106 dB and THD+N of 0.002% at 192 kHz sampling rate.
• Flexible Control Interface: Features a three-wire serial interface supporting standard audio data formats and user-programmable functions via register writes.
• Wide Input Support: Compatible with industry-standard audio data formats including 16-bit and 24-bit data.

ADCs/DACs - Special Purpose Applications

• Audio Digital Signal Processors (DSPs)
• Audio Decoder Chips
• Home Theater Systems
• Professional Audio Equipment

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DBQR' against the manufacturer's datasheet to confirm the package type (SSOP-16) and tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range of -25°C to +85°C for the target application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component when high-resolution 24-bit audio conversion is required with low jitter tolerance. It serves as a pin-compatible alternative to the PCM1748, PCM1742, and PCM1741, excluding pin 5 differences. Consider the PCM1754 if hardware-only control without serial interface programming is preferred.

ADCs/DACs - Special Purpose Part Context

The PCM1753DBQR belongs to the PCM175x family, which also includes the PCM1754 and PCM1755. These devices share the same core enhanced delta-sigma architecture but differ in control interfaces; the PCM1753 specifically utilizes a software-controlled serial interface, whereas the PCM1754 relies on hardware pins for configuration.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1754DBQR is a functional substitute within the same family, differing primarily in its hardware-based control mechanism instead of the serial interface found in the PCM1753. Other pin-compatible options include the PCM1748, PCM1742, and PCM1741, noting that pin 5 configurations may vary.
