The LM75A, LM75B and LM75C are a family of industy-stan-dard digital temperature sensors with an integrated Sigma-Delta analog-to-digital converter and PC interface. The LM75 provides 9-bit digital temperature readings with an ac-curacy of ±2℃ from-25℃ to 100℃ and ±3C over-55℃ to 125℃.
The LM75A operates with a single supply from +2.7V to +5.5V. Communication is accomplished over a 2-wire inter-face which operates up to 400kHz. The LM75 has three address pins, allowing up to eight LM75 devices to operate on the same 2-wire bus. The LM75 has a dedicated over-temperature output (O.S.) with programmable limit and hys. tersis. This output has programmable fault tolerance, whichallows the user to define the number of consecutive error conditions that must occur before O.S. is activated.
The wide temperature and supply range and IPC interface make the LM75 ideal for a number of applications incduding base stations, electronic test equipment, office electronics, personal computers, and any other system where thermalmanagement is critical to performance. The LM75A, LM75B and LM75C are available in an SOP-8 pacakage. The LM75B and LM75C are available in an MSOP-8 package.
