11 Device and Documentation Support

11.1 Device Support

11.1.1 Device Nomenclature

The device performance is characterized by the signal, responsivity, and the noise of the sensor. The sensor

noise can be characterized in terms of the raw sensor voltage, or in terms of a reference system with known

optical transfer function.

Responsivity A measure of the voltage generated by the thermopile as a function of the thermal radiation

incident on the device. The responsivity is measured in V/W. Typically incident radiations are in µW

and sensor output voltages in µV.

Sensor Noise The noise voltage intrinsic to the sensor given in nV. This parameter is conversion-time

dependent.

Noise Equivalent Power (NEP) The smallest thermal power difference that the detector can reliably detect;

measured in nW. The NEP is a function of the sensor noise and the responsivity.

Noise Equivalent Temperature Difference (NETD) The smallest temperature difference the detector can

reliably detect; measured in milliKelvins (mK). The NETD is a function of the sensor noise,

responsivity and the system specific optical path.

For comparison purposes, NETD is given for a reference system without a lens and with an

ideal (nonabsorbing) F/1 lens.

11.5 Electrostatic Discharge Caution

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
