DESCRIPTION
The LMT84/LMT84-Q1 are precision analog output
CMOS integrated-circuit temperature sensors that
operates at a supply voltage as low as 1.5 Volts. A
class-AB output structure gives the LMT84/LMT84-
Q1 strong output source and sink current capability
for driving heavy loads. This means it is well suited to
source the input of a sample-and-hold analog-to-
digital converter with its transient load requirements.
While operating over the wide temperature range of
−50°C to 150°C, the LMT84/LMT84-Q1 deliver an
output voltage that is inversely proportional to
measured temperature. The LMT84/LMT84-Q1 low
supply current make it ideal for battery-powered
systems as well as general temperature sensing
applications.
The LMT84/LMT84-Q1 can operate with a 1.5V
supply while measuring temperature over the full
−50°C to 150°C operating range.
The LMT84/LMT84-Q1 are cost-competitive
alternatives to thermistors.
