ADS8344
inputs provide a differential input. See Tables I and II and
Figure 2 for more information. The last two bits (PD1 - PD0)
select the power-down mode and clock mode as shown in
Table V. If both PD1 and PD0 are HIGH, the device is
always powered up. If both PD1 and PD0 are low, the device
enters a power-down mode between conversions. When a
new conversion is initiated, the device will resume normal
operation instantly—no delay is needed to allow the device
to power up and the very first conversion will be valid.
Clock Modes
The ADS8344 can be used with an external serial clock or
an internal clock to perform the successive-approximation
conversion. In both clock modes, the external clock shifts
data in and out of the device. Internal clock mode is selected
when PD1 is HIGH and PD0 is LOW.
External Clock Mode
In external clock mode, the external clock not only shifts
data in and out of the ADS8344, it also controls the A/D
conversion steps. BUSY will go HIGH for one clock period
after the last bit of the control byte is shifted in. Successive-
approximation bit decisions are made and appear at DOUT
on each of the next 16 SCLK falling edges (Figure 3). Figure
4 shows the BUSY timing in external clock mode.

Power-down between conversions. When each
conversion is finished, the converter enters a low
power mode. At the start of the next conversion,
the device instantly powers up to full power. There
is no need for additional delays to assure full
