High-Precision Digital Thermometer and Thermostat

Description

The DS7505 low-voltage (1.7V to 3.7V) digital thermometer and thermostat provides 9-, 10-, 11-, or 12-bit digital temperature readings over a -55°C to +125°C range with ±0.5°C accuracy over a -0°C to +70°C range. A 9-bit resolution mode is software compatible with the LM75.The DS7505 thermostat has a dedicated open-drain output (O.S.) and programmable fault tolerance, which allows the user to define the number of consecutive error conditions that must occur before O.S. is activated. There are two thermostatic operating modes that control thermostat operation based on user-defined trip points (TOSand THYST) that are stored in EEPROM registers.ApplicationsAny Thermally Sensitive SystemCellular Base StationsMedical EquipmentNetworking EquipmentOffice Equipment
