8.4.4 Startup Times
Table 16 lists the startup times for the analog output paths. For each case, the device has been previously
configured for a known Fs with all clocks applied (see “Lock Time” on page 130 for the length of this initial
period). The times recorded in the table are from when the PDN bit is cleared until the output path pro-
duces full-scale audio at the output pins of the device. If a soft ramp is enabled, the setting is 1/8 dB per
Fs. The values in Table 16 assume fast start mode is not being used; see Table 13 in Section 4.17.
