Note 1:
All devices are 100% tested at T
A
= +25
°
C. Limits over temperature are guaranteed by design.
Note 2:
SHDN
is available on the MAX4475/MAX4488 only.
Note 3:
Guaranteed by the PSRR test.
Note 4:
Guaranteed by design.
Note 5:
Full-power bandwidth for unity-gain stable devices (MAX4475
MAX4478) is measured in a closed-loop gain of +2V/V to
accommodate the input voltage range, V
OUT

Note 6:
Lowpass-filter bandwidth is 22kHz for f = 1kHz and 80kHz for f = 20kHz. Noise floor of test equipment = 10nV/
Hz
