NOTE: RC COMPENSATION BETWEEN PINS 11 AND 13 IS
REQUIRED ONLY FOR CLOCK-TUNABLE OPERATION FOR:
50kHz < fCUTOFFs ≤ 100kHz.
15pF
THE TEST SPECIFICATIONS FOR:
fCLK = 2MHz, fCUTOFF = 40kHz, AND
fCLK = 4MHz, fCUTOFF = 80kHz
INCLUDE THE EFFECTS OF RC COMPENSATION.

COMPENSATION DOES NOT INFLUECE THE SPECIFICATIONS
FOR:
fCLK = 400kHz, fCUTOFF = 8kHz.
FOR CLOCK-TUNABLE fCUTOFFs FROM 2kHz TO 50kHz
COMPENSATION IS NOT REQUIRED AND THE FILTER’S
PASSBAND PERFORMANCE IS REPRESENTED BY THE
TYPICAL SPECIFICATIONS AT:
fCLK = 400kHz, fCUTOFF = 8kHz.
