TYPICAL APPLICATION

FEATURES

DESCRIPTION

Remote/Internal

Temperature Sensor

TheLTC®2997isahigh-accuracyanalogoutputtemperature

sensor. It converts the temperature of an external sensor or

its own temperature to an analog voltage output. A built-in

algorithm eliminates errors due to series resistance be-

tween the LTC2997 and the sensor diode.

The LTC2997 gives accurate results with low-cost diode-

connected NPN or PNP transistors or with integrated

temperature transistors on microprocessors or FPGAs.

Tying pin D+ to VCC configures the LTC2997 to measure

its internal temperature.

The LTC2997 provides an additional 1.8V reference voltage

output which can be used as an ADC reference input or

for generating temperature threshold voltages to compare

against the VPTAT output.

The LTC2997 provides a precise and versatile micropower

solution for accurate temperature sensing.
