The power-on reset (POR) circuit generates a reset signal at typically 2.2 V; this circuit does not depend on the

other power supplies: VCCDA, VCCAD, VCCH, and VCCP. The internal circuit is cleared to default status, then all

analog and digital outputs have no signal. It is recommended to turn the device on and off as shown in Figure 31,

in order to avoid loud, audible pop noises when powering the device on or off.

RSTB is active low. 100 ns (minimum) is needed for an effective reset to the internal circuit.
