MAX4731/MAX4732/MAX4733
50 Ω, Dual SPST Analog Switches in UCSP
_______________________________________________________________________________________ 5
Note 3: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 4: UCSP and TDFN parts are 100% tested at +25°C only, and guaranteed by design over temperature. µMAX parts are
100% tested at +85°C and +25°C and guaranteed by design over temperature.
Note 5: ∆R

.
Note 6: UCSP on-resistance matching between channels and on-resistance flatness guaranteed by design.
Note 7: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 8: Guaranteed by design.
Note 9: Off-Isolation = 20 log
