LM70 Datasheet (National Semiconductor) - SPI/MICROWIRE 10-Bit plus Sign Digital Temperature Sensor

LM70, SPI/MICROWIRE 10-Bit plus Sign Digital Temperature Sensor

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
