___________Applications Information
Operation with Supply Voltages
Other Than ±15VO
Using supply voltages other than ±15V is reduces the
analog signal range. The MAX361/MAX362 switches
operate with bipolar supplies of ±4.5V to ±20V. Typical
operating characteristic graphs show typical on resis-
tance for ±15V, ±10V, and ±5V supplies. Switching
times increase by a factor of two or more for ±5V oper-
ation. The MAX361/MAX362 can also operate from
+10V to +30V unipolar supplies. Both parts can also
be powered from unbalanced supplies such as +24V
and -5V. Connect V- to 0V when operating with a sin-
gle supply.
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings, because stresses beyond the listed rat-
ings may cause permanent damage to the devices.
Always sequence V+ on first, followed by V-, and logic
inputs. If power-supply sequencing is not possible,
add two small signal diodes in series with the supply
pins for overvoltage protection (Figure 6). Adding the
diodes reduces the analog signal range to 1V below
V+ and 1V below V-, but low switch resistance and low
leakage characteristics are unaffected. Device opera-
tion is unchanged, and the difference from V+ to V-
should not exceed +44V.
