DS2422 - Maxim Integrated

DS2422 1-Wire Temperature/Datalogger

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 .
