The • Up to Eight LM75s Can be Connected to a Single LM75 provides 9-bit digital temperature readings with Bus an accuracy of ±2°C from -25°C to 100°C and ±3°C over –55°C to 125°C. • Power Up Defaults Permit Stand-alone Operation as Thermostat Communication is accomplished over a 2-wire interface which operates up to 400kHz. The LM75 • UL Recognized Component (LM75B and LM75C) has three address pins, allowing up to eight LM75 • Key Specifications: devices to operate on the same 2-wire bus. The – Supply Voltage LM75 has a dedicated over-temperature output (O.S.) – LM75B, LM75C: 3 V to 5.5 V with programmable limit and hystersis. This output has programmable fault tolerance, which allows the – Supply Current user to define the number of consecutive error – Operating: 280 μA (typical) conditions that must occur before O.S. is activated. – Shutdown: 4 μA (typical) The wide temperature and supply range and I2C – Temperature Accuracy interface make the LM75 ideal for a number of – −25°C to 100°C: ±2°C (maximum) applications including base stations, electronic test equipment, office electronics, personal computers, – −55°C to 125°C: ±3°C (maximum) and any other system where thermal management is critical to performance. The LM75B and LM75C are 2 Applications available in an SOIC package or VSSOP package. • General System Thermal Management Device Information(1) • Communications Infrastructure PART NUMBER PACKAGE BODY SIZE (NOM) • Electronic Test Equipment SOIC (8) 4.90 mm x 3.91 mm • Environmental Monitoring LM75B VSSOP (8) 3.00 mm x 3.00 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
