Specification Notes

[1] Above stated frequency, the amplifier becomes slew rate limited.
[2] The low frequency tolerance is accurate within ±20% of the specified frequency.
[3] Not to be used with low values of source resistance such as charge mode sensors at elevated temperatures or contaminated sensor cables (preventing low frequency peaking and/or output bias problems).
[4] Tested using voltage source and input capacitor equal to the feedback capacitor, to simulate a charge output sensor.
[5] See PCB Declaration of Conformance PS024 for details. A low impendance connection from case to earth ground is required to maintain CE compliance.
