The MAX11638/MAX11639/MAX11642/MAX11643 are
low-power, serial-output, multichannel ADCs with FIFO
capability for system monitoring, process-control, and
instrumentation applications. These 8-bit ADCs have
internal track-and-hold (T/H) circuitry supporting single-
ended inputs. Data is converted from analog voltage
sources in a variety of channel and data-acquisition con-

Figure 2 shows a simplified functional diagram of the
MAX11638/MAX11639/MAX11642/MAX11643 internal
architecture. The MAX11642/MAX11643 have 16 sin-
gle-ended analog input channels. The MAX11638/
MAX11639 have 8 single-ended analog input channels.
