Note 2:
SHDN is available on the MAX4249/MAX4251/MAX4253/MAX4256 only.
Note 3:
All device specifications are 100% tested at TA = +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. 4 Maxim Integrated
