DESCRIPTION
The LM95172EWG is an integrated digital-output
temperature sensor with a Serial Peripheral Interface
(SPI) and MICROWIRE?-compatible interface in a
10-pin Cerpack high temperature ceramic package. It
features a very linear Sigma-Delta Analog-to-Digital
Converter (ADC), high accuracy, fast conversion
rates, and extremely low output noise. With an
operating temperature as low as -40°C and optimized
accuracy from 120°C to 200°C, it is ideal for high-
temperature applications.
The over-temperature alarm output (OVERTEMP)
asserts when the die temperature exceeds a
programmed THIGH limit. The user-programmed TLOW
limit creates a temperature-stabilizing hysteresis
when the ambient temperature is near the trip point.
The LM95172EWG can be programmed to operate
from 13 bits (0.0625°C per LSB) to 16 bits
(0.0078125°C per LSB) resolution. The
LM95172EWG powers up in 35 ms, the fastest
conversion time, with temperature output set at 13-bit
resolution. The resolution may then be changed to
14-, 15- or 16-bits. When in the 13-, 14- or 15-bit
resolution mode, the least significant bit in the 16-bit
temperature register toggles after the completion of
each conversion. This bit may be monitored to verify
that the conversion is complete.
The high noise immunity of the Serial I/O (SI/O)
output makes the LM95172EWG ideal for use in
challenging electromagnetic environments.
