NJM2742
HIGH SPEED SINGLE SUPPLY OPERATIONAL AMPLIFIER
■
GENERAL DESCRIPTION
The
NJM2742
is a high speed single supply operational
amplifier .The low V
OL
enables to treat small output
signal on a single supply.
It has wide supply voltage range, +3 to +32 volt and
high slew rate.
The
NJM2742
is suitable for power supply and motor
driver units.

Note: The common mode input voltage range of NJM2742 is shifted toward the V- for single supply use.
At the low operating voltage, the center potential of the V+ and V- may be out of the common mode
voltage range. In this case, shift the common mode input voltage toward the V-.
