MAX4613 Maxim, MAX4613 Datasheet - Page 6

• Manufacturer Part Number: MAX4613
• Description: The MAX4613 quad analog switch features on-resistance matching (4Ω max) between switches and guarantees on-resistance flatness over the signal range (9Ω max)
• Manufacturer: Maxim

Using supply voltages less than ±15V will reduce the
analog signal range. The MAX4613 operates with
±4.5V to ±20V bipolar supplies or with a +4.5V to +40V
single supply; connect V- to GND when operating with
a single supply. Also, all device types can operate with
unbalanced supplies such as +24V and -5V. V
be connected to +5V to be TTL compatible, or to V+ for
CMOS-logic level inputs. The Typical Operating
Characteristics graphs show typical on-resistance with
±20V, ±15V, ±10V, and ±5V supplies. (Switching times
increase by a factor of two or more for operation at ±5V.)
Proper power-supply sequencing is recommended
for all CMOS devices. Do not exceed the absolute
maximum ratings because stresses beyond the list-
ed ratings may cause permanent damage to the
devices. Always sequence V+ on first, followed by

is not possible, add two small, external signal
diodes in series with supply pins for overvoltage
protection (Figure 1). Adding diodes reduces the
analog signal range to 1V below V+ and 1V above
V-, but low switch resistance and low leakage char-
acteristics are unaffected. Device operation is
unchanged, and the difference between V+ and V-
should not exceed +44V.
