A recently released low distortion and high dynamic range delta-sigma DAC achieves a dynamic range of 107 dB and full-scale total harmonic distortion + noise (THD+N) of 101 dB. This level of performance can be achieved with an understanding of 1-bit technology and thoughtful system design. The development of a DAC system employing this device will be discussed including the use of optocouplers, clock jitter attenuator, off-chip 1-bit latch, and analog filtering.
