... Junction temperature rating due to power dissipation must also be observed. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... The gain accuracy is primarily determined by the matching of the two gain resistors, R voltage gain error of the MAX9937 is less than 1.5%. Total gain = 20V/V with R Low temperature drift of input bias currents and input offset currents minimizes their impact on total input off- set voltage of the current-sense amplifier. ...

... Similarly, capacitor C ter the output voltage, thus providing not only differen- tial filtering, but also filtering for input common-mode transients that have made it past the MAX9937. The corner frequency of this filter is similarly determined by choice of R current-output device, and has the ability to drive an infinite amount of load capacitance ...
