__________Applications Information
Operation with Supply Voltages
Other than ±15Vo
The main limitation of supply voltages other than ±15V is
a reduction in the analog signal range. The MAX333A
operates with ±5V to ±20V bipolar supplies. The
Typical Operating Characteristics and graphs show typ-
ical on resistance for ±15V, ±10V, ±5 supplies.
Switching times increase by a factor of two or more for
±5V operation. The MAX333A can operate from +10V
to +24V unipolar supplies. It can be powered from a
single +10V to +24V supply, as well as from unbalanced
supplies such as +24V and -5V. Connect V- to 0V when
operating with a single supply.
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 ratings 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 (Figure 1). Adding the diodes reduces the
analog signal range to 1V below V+ and 1V below V-,
but low switch resistance and low leakage characteris-
tics are unaffected.
