Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Applies over input voltage range limit and includes gain
uncertainty.
Note 3: Center error = [(VU +VL)/2 – CENTER] (where VU = upper band
limit and VL = lower band limit).
Note 4: Width error = (VU –VL – 2 WIDTH/2) (where VU = upper band
limit and VL = lower band limit).
Note 5: RIN is guaranteed by design and is not tested. RIN = 1/(fS x 66pF).
Note 6: Average supply current = TD lS(ON) fS + (1 –TD fS) IS(OFF).
Note 7: Response time is set by an internal oscillator and is independent
of overdrive voltage. TD is guaranteed by correlation test and is not directly
measured.
