Datasheet MAX4519MJD, MAX4519ESD, MAX4519EPD, MAX4519EEE, MAX4519CSD Datasheet (Maxim)

________________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 leak­age 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.

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.

Note 2: 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 3: Guaranteed by design.
Note 4: ∆R

ON

= RON(max) - RON(min).

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

NO

= 3V to 0V and 0V to -3V.

Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
Note 7: 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.

__________Applications Information

Operation with Supply Voltages

Other than ±5V

Using supply voltages less than ±5V reduces the analog
signal range. The MAX4518/MAX4519 muxes operate
with ±2.7V to ±8V bipolar supplies or with a +2.7V to
+15V single supply. Connect V- to GND when operating
with a single supply. Both device types can also operate
with unbalanced supplies, such as +10V and -5V. The

Typical Operating Characteristics

graphs show typical
on-resistance with ±3V, ±5V, +3V and +5V supplies.
(Switching times increase by a factor of two or more for
operation at 5V.)

Overvoltage Protection

Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi­mum ratings, because stresses beyond the listed rat­ings can cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs, NO, or COM. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with supply pins for overvoltage protection
(Figure 1). Adding diodes reduces the analog signal
range to one diode drop below V+ and one diode drop

above V-, but does not affect the devices’ low switch
resistance and low leakage characteristics. Device
operation is unchanged, and the difference between
V+ and V- should not exceed 17V. These protection
diodes are not recommended when using a single supply.
