Product Overview
The DS28EA00 is a digital thermometer with 9-bit (0.5°C) to 12-bit (1/16°C) resolution and alarm function with nonvolatile (NV), user-programmable upper and lower trigger points. Each DS28EA00 has its own unique 64-bit registration number that is factory programmed into the chip. Data is transferred serially through the 1-Wire® protocol, which requires only one data line and a ground reference for communication. The improved 1-Wire front-end with hysteresis and glitch filter enables the DS28EA00 to perform reliably in large 1-Wire networks.
- Digital Thermometer Measures Temperatures from -40°C to +85°C
- Thermometer Resolution is User Selectable from 9 to 12 Bits
- Unique 1-Wire Interface Requires Only One Port Pin for Communication
- Each Device Has a Unique 64-Bit, FactoryLasered Registration Number
- Multidrop Capability Simplifies Distributed Temperature-Sensing Applications
- Improved 1-Wire Interface with Hysteresis and Glitch Filter
- User-Definable NV Alarm Threshold Settings/User Bytes
- Alarm Search Command to Quickly Identify Devices Whose Temperature is Outside of Programmed Limits
- Standard and Overdrive 1-Wire Speed
- Any Rack-Based Electronic System; Climate Control; Data communication equipment; Process Temperature Monitoring; Servers; Wireless Basestations
Applications
Datacom, HVAC
