temperature range.

Note 1: The maximum clock frequency criterion is arbitrarily defined as:

The frequency at which the filter AC response exhibits

≥ 1dB of gain

peaking.

frequency can be as low as 10Hz. The minimum clock frequency is

arbitrarily defined as: the clock frequency at which the output DC offset

changes by more than 1mV.

Note 3: The wideband noise specification does not include the clock

feedthrough.

Note 4: To properly evaluate the filter’s harmonic distortion an inverting

output buffer is recommended as shown in the Test Circuit. An output

buffer is not necessarily needed when measuring output DC offset or

wideband noise.

Note 5: The output DC offset is optimized for

±5V supply. The output DC

offset shifts when the power supplies change; however this phenomenon

is repeatable and predictable.
