Overview
The LM95071CIMF is a high-resolution digital temperature sensor produced by Texas Instruments (though it was originally developed by National Semiconductor, which is now part of TI). This device features an SPI and MICROWIRE compatible interface, making it versatile for various applications requiring precise temperature measurement. The LM95071CIMF operates over a wide temperature range of -40°C to 150°C with an accuracy of ±1°C from 0°C to 70°C and ±2°C over the entire range. It is packaged in a compact 5-pin SOT-23 form factor, which is ideal for space-constrained designs.
