n Reset function
When RSTN = “0”, the DAC is powered down but the internal register values are not initialized. The analog outputs go
to VCOM voltage and DZF pin goes to “H”. Figure 12 shows the sequence of reset by RSTN bit.
Notes:
MS0014-E-02
(1) The analog output corresponding to digital input has the group delay (GD).
(2) Analog outputs go to VCOM voltage.
(3) Click noise occurs at the edges(“
(4) The external clocks (MCKI, BICK and LRCK) can be stopped in the reset mode (RSTN = “L”).
(5) DZF pin goes to “H” when the RSTN bit becomes “0”, and goes to “L” at 4~5/fs after RSTN bit becomes “1”.
(6) There is a delay, 2~3/fs from RSTN bit “1” to the internal RSTN “1”.
