LM70

·0.25°C temperature resolution.
·Shutdown mode conserves power between temperature reading
·SPI and MICROWIRE Bus interface
· MSOP-8 and LLP-8 packages save space

The LM70 is a temperature sensor, Delta-Sigma analog-to-digital 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 µA. This mode is useful in systems where low average power consumption is critical.

The LM70 has 10-bit plus sign temperature resolution (0.25°C per LSB) while operating over a temperature range of −55°C to +150°C.

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.
