M
If the internal reference is used and R/
W
= 0, shutdown
occurs when the master issues a not-acknowledge bit
while reading the conversion results. The internal refer-
ence and internal reference buffer are disabled during
shutdown, reducing the analog supply current to less
than 1μA.
A dummy conversion is required to power up the inter-
nal reference. The MAX1069 internal reference begins
powering up from shutdown on the 9th falling edge of a
valid address byte. Allow 12ms for the internal refer-
ence to settle before obtaining valid conversion results.
Reference Voltage
The MAX1069 provides an internal or accepts an exter-
nal reference voltage. The ADC input range is from
V
AGNDS
to V
REF
(see the
Transfer Function
section).
