Product Details
Key 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: 2.5mW active, 25µW idle
- Built-in multidrop controller allows multiple DS2450's 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 16.3k bits per second
- Overdrive mode boosts communication speed to 142k bits per second
- On-chip 16-bit CRC-generator for safeguarding data transfers
- Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number 8-bit CRC tester) assures absolute traceability because no two parts are alike
- 8-bit family code specifies device communication requirements to bus master
- Operating temperature range from -40°C to +85°C
- Compact, low cost 8-pin SOIC surface mount package
