Pin Description
Applications Information
Operation with Supply Voltages
Other than ±15V
The MAX4621/MAX4622/MAX4623 switches operate with
±4.5V to ±18V bipolar supplies and a +4.5V to +36V sin-
gle supply. In either case, analog signals ranging from
V+ to V- can be switched. The
Typical Operating
Characteristics graphs show the typical on-resistance
variation with analog signal and supply voltage.
Overvoltage Protection
Proper power-supply sequencing is recommended for all
CMOS devices. It is important not to exceed the absolute
maximum ratings because stresses beyond the listed rat-
ings may cause permanent damage to the devices.
Always sequence V+ on first, followed by VL, V-, and
logic inputs. If power-supply sequencing is not possible,
add two small signal diodes in series with the supply pins
and a Schottky diode between V+ and VL (Figure 1).
Adding diodes reduces the analog signal range to 1V
below V+ and 1V above V-, but low switch resistance and
low leakage characteristics are unaffected. The differ-
ence between V+ and V- should not exceed +44V.
