LM70
SPI/MICROWIRE
10-Bit plus Sign Digital Temperature
Sensor
General Description
The
LM70
is
analog-to-digital converter with an SPI and MICROWIRE
compatible interface available in LLP and MSOP 8-pin pack-
ages. The host can query the LM70 at any time to read tem-
perature. 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
(0.25C 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, elec-
tronic test equipment, and office electronics.
