Bypass and Decoupling Capacitor Requirements
Various sized decoupling capacitors can be used, with no special tolerances being required. All capacitors must be
located as close as possible to the appropriate pins of the DSD1793 to reduce noise pickup from surrounding circuitry.
Aluminum electrolytic capacitors that are designed for hi-fi audio applications are recommended for larger values,
while metal film or monolithic ceramic capacitors are used for smaller values.
Post-LPF Design
By proper choice of the op amp and resistors used in the post-LPF circuit, excellent performance of the DSD1793
should be achieved. To obtain 0.001% THD+N and 113 dB signal-to-noise-ratio audio performance, the THD+N and
input noise performance of the op amp should be considered. This is because the input noise of the op amp
contributes directly to the output noise level of the application. The VOUT pin of the DSD1793 and the input resistor
of the post-LPF circuit must be connected as closely as possible.
Out-of-band noise level and attenuated sampling spectrum level are much lower than for typical delta-sigma type
DACs due to the combination of a high-performance digital filter and advanced segment DAC architecture. The use
of a second-order or third-order post-LPF is recommended for the post-LPF of the DSD1793. The cutoff frequency
of the post-LPF depends on the application. For example, there are many sampling-rate operations such as fS = 44.1
kHz on CDDA, fS = 96 kHz on DVD-M, fS = 192 kHz on DVD-A, fS = 64 fS on DSD (SACD).
