The MAX1026/MAX1028/MAX1030 are low-power, seri-
al-output, multichannel ADCs with temperature-sensing
capability for temperature-control, process-control, and
monitoring applications. These 10-bit ADCs have inter-
nal track and hold (T/H) circuitry that supports single-
ended and fully differential inputs. Data is converted
from an internal temperature sensor or analog voltage
sources in a variety of channel and data-acquisition

configurations. Microprocessor (μP) control is made
easy through a 3-wire SPI/QSPI/MICROWIRE-compati-
ble serial interface.
Figure 2 shows a simplified functional diagram of the
MAX1026/MAX1028/MAX1030 internal architecture. The
MAX1026 has eight single-ended analog input chan-
nels or four differential channels. The MAX1028 has 12
single-ended analog input channels or six differential
channels. The MAX1030 has 16 single-ended analog
input channels or eight differential channels.
