The MAX11626–MAX11629/MAX11632/MAX11633 are
low-power, serial-output, multichannel ADCs with FIFO
capability for system monitoring, process-control, and
instrumentation applications. These 12-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-
figurations. Microprocessor (µP) control is made easy

Figure 2 shows a simplified functional diagram of the
MAX11626–MAX11629/MAX11632/MAX11633 internal
architecture. The MAX11632/MAX11633 have 16 sin-
gle-ended analog input channels. The MAX11628/
MAX11629 have 8 single-ended analog input channels.
The MAX11626/MAX11627 have 4 single-ended analog
input channels.
