SBAS350F – JUNE 2005 – REVISED FEBRUARY 2008
When powering up the ADS1232/34, AVDD and
DVDD must be powered up before the PDWN pin
goes high, as shown in Figure 39. If PDWN is not
controlled by a microprocessor, a simple RC delay
circuit must be implemented, as shown in Figure 40.
Figure 39. Power-Up Timing Sequence
Power-Down mode shuts down the entire ADC
circuitry and reduces the total power consumption
close to zero. To enter Power-Down mode, simply
hold the PDWN pin low. Power-Down mode also
resets the entire circuitry to free the ADC circuitry
from locking up to an unknown state. Power-Down
mode can be initiated at any time during readback; it
is not necessary to retrieve all 24 bits of data
beforehand. Figure 41 shows the wake-up timing
from Power-Down mode.

Value given for fCLK = 4.9152MHz. For different fCLK frequencies, the scale is proportional to the CLK period except for a ±3% variation
when an internal oscillator is used.
