DESCRIPTION
The DSD1700 is a unique digital-to-analog converter designed for DSD audio applications. The DSD1700 consists of a single-channel, 8-tap analog FIR filter constructed using a double differential circuit architec- ture, ensuring excellent dynamic performance and high power- supply noise rejection. The DSD1700 also includes the necessary logic required to interface directly to a DSD decoder IC. The overall features and performance of the DSD1700 make it an ideal choice for high-performance Super Audio CD players and DSD studio applications.

SPECIFICATIONS All specifications TA = +25°C, VDD = VCC = 5.0V, fS = 44.1kHz, data clock = 64fS, system clock = 256fS, unless otherwise specified. (Although the sampling frequency of Direct Stream Digital is 2.8224MHz, for convenience, in this specification sheet, it is described that the sampling frequency (fS) is 44.1kHz and the 2.8224MHz clock is 64fS).

This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degrada- tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. NOTE: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. (2) VCC , VDD . (3) Among VCC , VDD .
