TDA1547 - NXP

TDA1547 Dual top-performance bitstream DAC

The TDA1547 is a dedicated one-bit digital-to-analog converter to facilitate a high fidelity sound reproduction of digital audio. The TDA1547 is extremely suitable for use in high quality audio systems such as Compact Disc and DAT players, or in digital amplifiers and digital signal processing systems. The TDA1547 is used in combination with the SAA7350 bits.
