Typical Operating Characteristics
(VIN = +5V (MAX4838A/MAX4840A), VIN = +4V (MAX4842A); Si9936DY external MOSFET in back-to-back configuration; TA = +25°C,
unless otherwise noted.)
Note 1: All parts are 100% tested at +25°C. Electrical limits across the full temperature range are guaranteed by design and
correlation.
