SBAS428D – JANUARY 2008 – REVISED JUNE 2012

POWER-DOWN TIMING

Power-up time shown is based on 1

μF bypass capacitors on the reference pins. tWAKE is the time it takes for the device to wake up

completely from power-down mode. The ADS5287 has two power-down modes: complete power-down mode and partial power-down mode.

The device can be configured in partial power-down mode through a register setting.

tWAKE < 50μs for complete power-down mode.

tWAKE < 2μs for partial power-down mode (provided the clock is not shut off during power-down).
