LM70 is a 10-bit temperature sensor produced by TI. It supports SPI and MICROWIRE protocol. The measurement range is -55~150℃. The operating voltage is 2.65~5.5V and the supply current is 260uA (typical)~490uA (maximum). The standby current is 12uA (typical).
The LM70 is a Delta-Sigma analog-to-digital converter designed for thermal management applications in personal computers, disk drives, printers, and electronic test equipment. It features an SPI and MICROWIRE compatible interface available in LLP-8 and MSOP-8 packages. The device includes a shutdown mode to decrease power consumption to less than 10µA.
