LTC2997 - Remote/Internal Temperature Sensor

General Description

The LTC®2997 is a high-accuracy analog output temperature 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 between the LTC2997 and the sensor diode.

LTC2997 Remote/Internal Temperature Sensor FEATURES n n n n n n n n n n DESCRIPTION The LTC®2997 is a high-accuracy analog output temperature 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 between the LTC2997 and the sensor diode. The LTC2997 gives accurate results with low-cost diodeconnected 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.
