Maxim Integrated 

SOT23, Single-Supply, Low-Noise,

Low-Distortion, Rail-to-Rail Op Amps

ELECTRICAL CHARACTERISTICS (continued)

(VDD = +5V, VSS = 0V, VCM = 0V, VOUT = VDD/2, RL tied to VDD/2, SHDN = VDD or open, TA = -40°C to +85°C, unless otherwise

noted. Typical values are at TA = +25°C.) (Notes 1, 2)

Note 1: SHDN is available on the MAX4249/MAX4251/MAX4253/MAX4256 only.

Note 2: The MAX4249EUB, MAX425_EU_ specifications are 100% tested at TA = +25°C. Limits over the extended temperature

range are guaranteed by design, not production tested.

Note 3: Guaranteed by the Power-Supply Rejection Ratio (PSRR) test.

Note 4: Guaranteed by design.

Note 5: Lowpass filter bandwidth is 22kHz for f = 1kHz, and 80kHz for f = 20kHz. Noise floor of test equipment = 10nV/√Hz.
