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 10M

Ω. The LTC1563 can be used with even larger valued resistors.

When using very large values of resistance careful layout and thorough

The

● denotes specifications which apply over the full operating temperature range, otherwise specifications are TA = 25°C.

VS = Single 4.75V, EN pin to logic “low,” Gain = 1, RFIL = R11 = R21 = R31 = R12 = R22 = R32, specifications apply to both the high

speed (HS) and low power (LP) modes unless otherwise noted.

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.
