Note 1: All devices are 100% production tested at T
Note 2: Extrapolated to V
Note 3: Input offset voltage V
Note 4: Amplitude of V
Note 5: Gain error applies to current flow in either direction and is calculated by applying two values for V
Note 6: The device is stable for any capacitive load at V
