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

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