AVAILABLE DS2422 1-Wire Temperature/Datalogger with 8KB Datalog Memory GENERAL DESCRIPTION The DS2422 temperature/datalogger combines the core functions of a fully featured datalogger in a single chip. It includes a temperature sensor, realtime 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 application-specific 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.
