Applications Information
Operating Considerations for
High-Voltage Supply
The MAX4731/MAX4732/MAX4733 operate to +11V
with some precautions. The absolute maximum rating
for V+ is +12V (referenced to GND). When operating
near this region, bypass V+ with a minimum 0.1µF
capacitor to ground as close to the IC as possible.
Logic Levels
The MAX4731/MAX4732/MAX4733 are TTL compatible
when powered from a single +5V supply. When pow-
ered from other supply voltages, the logic inputs should
be driven rail-to-rail. For example, with a +11V supply,
IN1 and IN2 should be driven low to 0V and high to
11V. With a +3.3V supply, IN1 and IN2 should be dri-
ven low to 0V and high to 3.3V. Driving IN1 and IN2 rail-
to-rail minimizes power consumption.
