... The typical DC line regulation specification does not include the output voltage shift discussed in Section 5.0. Note 12: Guaranteed by design and characterization. Note 13: The input current is leakage only and is highest at high temperature typically only 0.001µA. The 1µA limit is solely based on a testing limitation and does not reflect the actual performance of the part. ...

... The LM94022 has four selectable gains, each of which can be selected by the GS1 and GS0 input pins. The output volt- age for each gain, across the complete operating temperature range is shown in the LM94022 Transfer Table, below. This table is the reference from which the LM94022 accuracy specifications (listed in the Electrical Characteristics section) are determined ...

... To ensure good thermal conductivity, the backside of the LM94022 die is directly attached to the GND pin (Pin 2). The temperatures of the lands and traces to the other leads of the LM94022 will also affect the temperature reading. Alternatively, the LM94022 can be mounted inside a sealed- end metal tube, and can then be dipped into a bath or screwed into a threaded hole in a tank ...

... Most CMOS ADCs found in microcontrollers and ASICs have a sampled data comparator input structure. When the ADC charges the sampling cap, it requires instantaneous charge from the output of the analog source such as the LM94022 temperature sensor and many op amps. This requirement is easily accommodated by the addition of a capacitor (C on the size of the sampling capacitor and the sampling frequency ...
