A new current-mode multi-bit DAC has been designed to meet the needs of high-end audio with dynamic-range of 126dB and THD+N of 0.00025%. This performance is accomplished in monaural mode, which is constructed with 'L-channel DAC of plus and minus signal input and an external instrumentation amplifier configuration at the output. Each channel has dynamic-range of 123dB and THD+N for full-scale signal of 0.00025%. In this paper, the design concept of the chip, especially for analog design, is discussed.
