These DACs are designed for the serious audiophile. They utilize the best DAC chip -PCM1794A that is capable of producing a super dynamic range of 127dB in stereo mode and 132dB in mono mode! The I/V and analogy sections are custom designed and use 100% discrete components.

There is DAC with integrated circuit PCM1794A. It is one of execellent audio DACs from Burr Brown (Texas Instruments). It has 24-bit resolution, 192kHz sample frequency, 8x oversampling digital filter, differential current output and SNR 127dB. Circuit includes power supply, DAC and operational amplifier.

This simple but beautifully designed balanced DAC module is based on the integration of a pair of PCM1794A digital to analog conversion chips, each dedicated to a channel. These allow it to support sampling rates up to PCM 24bit 192kHz, while delivering a …

The PCM1794 is a monolithic CMOS integrated circuit that includes stereo digital-to-analog converters and support circuitry in a small 28-lead SSOP package. The data converters use TI’s advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter.

2018年4月27日 · I have been comparing the numbers on the current DAC chips and the Burr Brown (TI) 1794A has my attention. It has a S/N of 127 dB in stereo mode and 132 in mono mode. It has an "advanced segment" architecture and seems to be one of the better, if not the best, 24 bit DAC ICs in production.
