LM71 Datasheet | National Semiconductor

Description The LM71 is a low-power, high-resolution digital temperature sensor with an SPI and MICROWIRE patible interface, available in the 5-pin SOT23 or the 6-pin LLP (no pull back) package. The host can query the LM71 at any time to read temperature. Its low operating current is useful in systems where low power consumption is critical. The LM71 has 13-bit plus sign temperature resolution (0.03125˚C per LSB) while operating over a temperature range of - 40˚C to +150˚C. The LM71’s 2.65V to 5.5V supply voltage range, fast conversion rate, low supply current, and simple SPI interface make it ideal for a wide range of applications. n Electronic Test Equipment n Vending Machines Features n SOT23-5 or No-Pull-Back LLP-6 Packages n Operates over a full - 40˚C to +150˚C range n SPI and MICROWIRE Bus interface Key Specifications j Supply Voltage j Supply Current j Temperature 2.65V to 5.5V operating 300 µA (typ) 550 µA (max) Applications n n n n n System Thermal Management Personal puters Portable Electronic Devices Disk Drives Office Electronics Accuracy j Temperature - 10˚C to +65˚C - 40˚C to 150˚C ± 1.5˚C (max) +3/- 2˚C (max) 31.25 m˚C Resolution Simplified Block Diagram MICROWIRE™ is a trademark of National Semiconductor Corporation.
