LTC1562-2
ELECTRICAL CHARACTERISTICS The q denotes specifications that apply over the full operating temperature
range, otherwise specifications are at TA = 25°C. VS = ±5V, outputs unloaded, SHDN pin to logic “low”, unless otherwise noted. AC
specs are for a single 2nd order section, RIN = R2 = 10.4k ±0.1%, RQ = 9.09k ±0.1%, fO = 175kHz.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: fO change from ±5V to ±2.375 supplies is – 0.2% typical,
fO temperature coefficient magnitude, 25°C to 85°C, is
50ppm/°C typical.
As with the LTC1562, fO decreases with increasing temperature.
Note 3: Tighter frequency tolerance is available, consult factory.
