Precision, 4-Channel/Dual 2-Channel,
Low-Voltage, CMOS Analog Multiplexers
________________General Description
The MAX4518/MAX4519 precision, monolithic, CMOS
analog multiplexers (muxes) offer low on-resistance
(less than 100Ω), which is matched to within 4Ω
between channels and remains flat over the specified
analog signal range (10Ω max). They also offer low leak-
age over temperature (NO-off leakage current less than
2nA at +85°C) 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.

Note 1:
Signals on any terminal exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current ratings.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

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 +25°C.

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

Note 8:
Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
