3 . Chip Overview
GXT84/85/86/87 are a series of analog temperature sensors with negative temperature coefficients that provide an analog voltage output which is linearly proportional to the Celsius temperature. The GXT8X performs factory calibration, so no external calibration is required, with a typical accuracy of ±4°C at +25°C and a maximum accuracy of ±2.7°C in the temperature range from 40°C to + 125°C. 
GXT84/85/86/87 (the GXT8X series only include these four models) feature low-output impedance, linear output, and factory calibration, enabling significant simplification of temperature control circuits and ADC requirements. This series of sensor components can operate with a single power supply ranging from 1.5V to 5.5V. The power supply current is below 10μA, and the self-heating effect is minimal, with a temperature change of less than 0.1°C in static air. GXT84/85/86/87 are available in low-cost 5-pin SOT353 surface mount, 3-pin TO-92 and 3-pin TO92S packages.
