Note 2: SHDN is available on the MAX4249/MAX4251/MAX4253/MAX4256 only.
Note 3: All device specifications are 100% tested at T
A
= +25°C. Limits over temperature are guaranteed by design.
Note 4: Guaranteed by the PSRR test.
Note 5: Offset voltage prior to reflow on the UCSP.
Note 6: Guaranteed by design.
Note 7: Lowpass-filter bandwidth is 22kHz for f = 1kHz and 80kHz for f = 20kHz. Noise floor of test equipment = 10nV/√Hz.
