V
REF
PIN
To ensure low source impedance of the ADC references, 0.1-
μ
F ceramic and 10-
μ
F electrolytic capacitors are
recommended between V
REF
and AGND. These capacitors should be located as close as possible to the V
REF
pin to reduce dynamic errors on the ADC references.

APPLICATION INFORMATION (continued)
The DOUT pin has a large load-drive capability, but if the DOUT line is long, locating a buffer near the PCM1807
and minimizing load capacitance is recommended to minimize the digital-analog crosstalk and maximize the
dynamic performance of the ADC.
The quality of the system clock can influence dynamic performance, as the PCM1807 operates based on a
system clock. Therefore, it may be necessary to consider the system clock duty, jitter, and the time difference
between system clock transition and BCK or LRCK transition in slave mode.
