Note 1:
SHDN
is available on the MAX4249/MAX4251/MAX4253/MAX4256 only.
Note 2:
The MAX4249EUB, MAX425_EU_ specifications are 100% tested at T
A
= +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/
