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 MAX1169 internal reference begins
powering up from shutdown on the 9th falling edge of a
58.6ksps, 16-Bit, 2-Wire Serial ADC
in a 14-Pin TSSOP
