Specification Notes

[1] Above stated frequency, the amplifier becomes slew rate limited.
[2] The low frequency tolerance is accurate within ±10% of the specified frequency.
[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.
