Note 1: Absolute Maximum Ratings are those value beyond which the life
of a device may be impaired.
Note 2: The minimum cutoff frequency of the LTC1563 is arbitrarily listed
as 256Hz. The limit is arrived at by setting the maximum resistor value
limit at 10MΩ. The LTC1563 can be used with even larger valued resistors.
When using very large values of resistance careful layout and thorough

assembly practices are required. There may also be greater DC offset at
high temperatures when using such large valued resistors.
Note 3: The cutoff frequency temperature drift at low frequencies is as
listed. At higher cutoff frequencies (approaching 25.6kHz in low power
mode and approaching 256kHz in high speed mode) the internal
amplifier’s bandwidth can effect the cutoff frequency. At these limits the
cutoff frequency temperature drift is ±15ppm/°C.
