________________General Description
The MAX4518/MAX4519 precision, monolithic, CMOS
analog multiplexers (muxes) offer low on-resistance
(less than 100
), which is matched to within 4
between channels and remains flat over the specified
analog signal range (10
max). They also offer low leak-
age over temperature (NO-off leakage current less than
2nA at +85C) and fast switching speeds (transition time
less than 250ns). The MAX4518 is a 4-channel device,
and the MAX4519 is a dual 2-channel device.
The MAX4518/MAX4519 are fabricated with Maxim's
low-voltage silicon-gate process. Design improvements
yield extremely low charge injection (less than 5pC) and
guarantee electrostatic discharge protection greater than
2000V.
These muxes operate with a single +2.7V to +15V supply
or with bipolar 2.7V to 8V supplies, while retaining
CMOS-logic input compatibility and fast switching. CMOS
inputs provide reduced input loading.

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 5:
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges; i.e., V

Note 6:
Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25C.

Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off isolation = 20log V
