Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The maximum clock frequency 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
frequency can be as low as 10Hz. The typical 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. An output buffer (although recommended)
is not necessarily needed when measuring output DC offset or wideband
noise (see Figure 3).
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.
Note 7: The LTC1065C is guaranteed to meet the specified performance
from 0°C to 70°C and is designed, characterized and expected to meet
specified performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC1065I is guaranteed to meet
specified performance from –40°C to 85°C.
