LM95071

LM95071 13-Bit Plus Sign SPI/MICROWIRE Temperature Sensor August 2004 LM95071 SPI/MICROWIRE™ 13-Bit Plus Sign Temperature Sensor General Description The LM95071 is a low-power, high-resolution digital temperature sensor with an SPI and MICROWIRE compatible interface, available in the 5-pin SOT23. The host can query the LM95071 at any time to read temperature. Its low operating current is useful in systems where low power consumption is critical. The LM95071 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 LM95071’s 2.4V 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.
