Output Offset vs Clock,
Medium Clock RatesSelf-Clocking Frequency vs R
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The maximum clock frequency criterion is arbitrarily defined as:
The frequency at which the filter AC response exhibits ≥ 1dB of gain
peaking.
Note 3: At limited temperature ranges (i.e., T
A
≤ 50°C) the minimum clock
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 4: The wideband noise specification does not include the clock
feedthrough.
Note 5: 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 6: 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.
