The MAX1098/MAX1099 are low-power, serial-output,
multichannel ADCs with temperature-sensing capability
for thermostatic, process-control, and monitoring appli-
cations. An algorithmic switched-capacitor converter
with T/H circuitry for both positive and negative inputs
supports fully differential 10-bit conversions from an
internal temperature sensor, two external temperature
sensors, or voltage sources in a variety of channel con-

figurations. Microprocessor (µP) control is made easy
through a flexible 3-wire serial interface.
Figure 1 shows a simplified functional diagram of the
MAX1098/MAX1099 internal architecture. In tempera-
ture-sensing mode, the multiplexer (mux) steers bias
currents through internal or external diodes while the
ADC computes their temperature in relation to changes
in forward voltage. Channels not used for temperature
measurement can be configured to measure other sys-
tem voltages.
