FEATURES
DESCRIPTION
The LMT86/LMT86-Q1 are precision analog output
CMOS integrated-circuit temperature sensors that
operates at a supply voltage as low as 2.2 Volts. A
class-AB output structure gives the LMT86/LMT86-
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 device delivers an output voltage
that is inversely proportional to measured
temperature. The LMT86/LMT86-Q1 low supply
current makes it ideal for battery-powered systems as
well as general temperature sensing applications.
