Dual 4-to-1 Multiplexers

Applications Information

Ground

V+ and GND power the internal logic and logic-level trans-

lators. The logic-level translators convert the logic-level

inputs to V+ and V- to drive the gates of the internal FETs.

In this design, there is no galvanic connection inside the

MAX4708/MAX4709 between the analog signal paths and

GND. ESD-protection diodes connect A_ to V+ and V-.

Supply Current Reduction

Driving the logic signals rail-to-rail from 0 to +15V or

-15V to +15V reduces the current consumption from

370µA (typ) to 200µA (typ) (see the Electrical Charac-

teristics table, Power Supplies).

Power Supplies

The MAX4708/MAX4709 operate with bipolar supplies

between ±4.5V and ±20V. The V+ and V- supplies

need not be symmetrical, but V+ - V- cannot exceed

the 44V absolute maximum rating.

The MAX4708/MAX4709 operate from single supplies

between +9V and +36V when V- is connected to GND.
