PCM1781DBQR Description

Short technical summary and product information.

The PCM1781DBQR from Texas Instruments is a 24-bit, 192-kHz sampling stereo digital-to-analog converter (DAC) designed for audio applications. It offers a high dynamic range of 106dB SNR and a low THD+N of 0.002%, ensuring high-quality audio reproduction.

 

This DAC utilizes a Delta-Sigma architecture and supports hardware control via I²S interface. It operates from a single 5V power supply and is housed in a compact 16-lead SSOP package, making it suitable for space-constrained designs. The device is specified for an operating temperature range of -25°C to 85°C.

 

Key features include a maximum sampling rate of 200kHz, a full-scale output of 3.9 Vp-p, and digital filter characteristics such as -50dB stop-band attenuation and ±0.04dB pass-band ripple. The PCM1781DBQR is pin-compatible with the PCM1680 and finds applications in A/V receivers, DVD players, HDTV receivers, and car audio systems.
