Overview
LM70 SPI/MICROWIRE10-Bit plus Sign Digital Temperature Sensor July 2000 LM70 SPI/MICROWIRE™ 10-Bit plus Sign Digital Temperature Sensor General Description 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.
