DS2422 Description
The DS2422 temperature/datalogger bines 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.
