MAX4708 Maxim, MAX4708 Datasheet - Page 11

• Manufacturer Part Number: MAX4708
• Description: The MAX4708/MAX4709 8-to-1 and dual 4-to-1 fault-protected multiplexers are pin compatible with the industry-standard DG508/DG509
• Manufacturer: Maxim

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-.
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-
teristic s table, 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.
