DS2450 Features
  • Four high-impedance inputs to measure analog voltages over the 1-Wire bus
  • User programmable input range (2.56V, 5.12V), resolution (1 to 16 bits) and alarm thresholds
  • 5V single supply operation
  • Very low power: 2.5µW active, 25µW idle
  • Built-in multidrop controller allows multiple DS2450s to be identified and operated on a common 1-Wire bus
  • Responds to Conditional Search if the analog voltage crosses the alarm thresholds
  • Channels not used as analog input can serve as open-drain digital outputs for closed-loop control
  • Directly connects to a single port pin of a microprocessor and communicates at up to 16.3kbps
  • Overdrive mode boosts communication speed to 142kbps
  • Unique, factory-lasered and tested 64-bit registration number assures absolute traceability because no two parts are alike
  • Operating temperature range from -40°C to +85°C
  • Compact, low-cost 8-pin SO surface-mount package
  • DS2450 Datasheet and Application Notes
