Standby/Partial Power Down Modes of Operation
Each ADC pair can be individually placed into partial power
down by bringing the CONVSTX signal low before the falling
edge of BUSY. To power the ADC pair back up again then the
CONVSTX signal should be brought high to tell the ADC pair
to power up and place the track-and-hold into track mode. In
partial power down mode the reference buffers will remain
powered up. While an ADC pair is in partial power down,
conversions can still occur on the other ADCs.
The AD7658/AD7657/AD7656 has a standby mode whereby
the device can be placed into a low current consumption mode
(0.5 μA max). The AD7658/AD7657/AD7656 is placed into
standby mode by bringing the logic input STBY low. The
AD7658/AD7657/AD7656 can be powered up again for normal
operation by bringing STBY logic high. The output data buffers
are still operational when the AD7658/AD7657/AD7656 is in
standby. This means the user can still continue to access the
conversion results when the AD7658/AD7657/AD7656 is in
standby. This standby feature can be used to reduce the average
power consumed by the AD7658/AD7657/AD7656 when
operating at lower throughput rates. The
AD7658/AD7657/AD7656 could be placed into standby at the
end of each conversion when BUSY goes low and taken out of
standby again prior to the next conversion. The time it takes for
the AD7658/AD7657/AD7656 to come out of standby is called
the “wake-up” time. This wake-up time will limit the maximum
throughput rate at which the AD7658/AD7657/AD7656 can
operate when powering down between conversions.
