ELECTRICAL CHARACTERISTICS (continued)
(VIN = +5V (MAX4943/MAX4944_/MAX4945_/MAX4949), VIN = +3V (MAX4946), TA = -40°C to +85°C, unless otherwise noted.
Typical values are at TA = +25°C.) (Note 1)
Note 1: All specifications are 100% production tested at TA = +25°C, unless otherwise noted. Specifications are over -40°C to +85°C
and are guaranteed by design.
