LM70 SPI/MICROWIRE 10-Bit plus Sign Digital Temperature Sensor
General Description
The LM70 is a temperature sensor, Delta-Sigma analog-todigital converter with an SPI and MICROWIRE compatible interface available in LLP and MSOP 8-pin packages. The host can query the LM70 at any time to read temperature. A shutdown mode decreases power consumption to less than 10 A. This mode is useful in systems where low average power consumption is critical. The LM70 has 10-bit plus sign temperature resolution (0.25C per LSB) while operating over a temperature range of 55C to +150C. The LM70’s 2.65V to 5.5V supply voltage range, low supply current and simple SPI interface make it ideal for a wide range of applications. These include thermal management and protection applications in hard disk drives, printers, electronic test equipment, and office electronics.
