The PCM1794ADB is a monolithic CMOS Integrated Circuit includes stereo digital-to-analogue converter. The data converter uses TI"s advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1794ADB provides balanced current outputs, allowing the user to optimize analogue performance externally. Sampling rates up to 200kHz are supported.
