Typical Operating Characteristics
(VDD = +5V, VSS = 0V, VCM = 0V, VOUT = VDD/2, RL tied to VDD/2, input noise floor of test equipment =10nV/√Hz for all distortion
measurements, TA = +25°C, unless otherwise noted.)

Maxim Integrated
Note 1: All devices are 100% tested at TA = +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, VOUT = 4VP-P.
Note 6: Lowpass-filter bandwidth is 22kHz for f = 1kHz and 80kHz for f = 20kHz. Noise floor of test equipment = 10nV/
√Hz.
