Detailed Description
The MAX1298/MAX1299 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 12-bit conversions from an
internal temperature sensor, two external temperature
sensors, or voltage sources in a variety of channel con-
figurations. Microprocessor (礟) control is made easy
through a flexible 3-wire serial interface.
Figure 1 shows a simplified functional diagram of the
internal architecture for the MAX1298/MAX1299. In tem-
perature-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 tem-
perature measurement can be configured to measure
other system voltages.
