GENERAL DESCRIPTION
The DS2422 temperature/datalogger combines the
core functions of a fully featured datalogger in a
single chip. It includes a temperature sensor, real-
time clock (RTC), memory, 1-Wire
interface, and
serial interface for an analog-to-digital converter
(ADC) as well as control circuitry for a charge pump.
The ADC and the charge pump are peripherals that
can
be
added
to
build
dataloggers. Without external ADC, the DS2422
functions as a temperature logger only. The DS2422
measures the temperature and/or reads the ADC at a
user-defined rate. A total of 8192 8-bit readings or
4096 16-bit readings taken at equidistant intervals
ranging from 1s 273hrs can be stored.
