IN-LINE CHARGE AMPLIFIER PCB Model 422E20
[1] Above stated frequency, the amplifier becomes slew rate limited.
[2] 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).
[3] Tested using voltage source and input capacitor equal to the feedback capacitor, to simulate a charge output sensor.
[4] See PCB Declaration of Conformance PS024 for details. A low impendance connection from case to earth ground is required to maintain CE compliance.
