NJM2744
High Speed Single Supply Quad Operational Amplifier
■
GENERAL DESCRIPTION
The
NJM2744
is a high-speed single supply quad
operational amplifier. The low V
OL
enables to treat small
output signal on a single supply.
It has wide supply voltage range, +3V to +32V and high
slew rate.
The
NJM2744
is suitable for power supply and motor
driver units.
