The sensor reset noise is sensitive to AVDDH and PVDD supplies. Therefore, linear regulators are recommended for supplying power to the AVDD and PVDD supplies. DC-DC regulators can be used to supply power to the rest of the supplies. Ripple voltage on the VMIX and the SUB_BIAS supplies must be kept at a minimum (< 50 mV) to minimize phase noise resulting from differences between quads. The VMIX regulator must have the bandwidth to supply surge current requirements within a short time of less than 10 µs after the integration period begins because VMIX currents have a pulsed profile.

There is no strict order for the power-on or -off sequence. The VMIX supplies are recommended to be turned on after all supplies have ramped to 90% of their respective values to avoid any power-up surges resulting from high VMIX currents in a non-reset device state.
