During the conversion process, SCLK is ignored. Only
after a conversion is complete will SCLK cause serial
data to be output. Falling edges on CNVST, during an
active conversion process, interrupt the current conver-
sion and cause the input multiplexer to switch to CH1.
To reinitiate a conversion on CH0, it is necessary to
Single-Supply, Low-Power,
2-Channel, Serial 8-Bit ADCs

allow for a conversion to be complete and all of the
data to be read out. Once a conversion has been com-
pleted, the MAX1117/MAX1118/MAX1119 will go into
AutoShutdown™ mode (<1µA typ) until the next conver-
sion is initiated.
