DESCRIPTION
The NJU77552 is a dual rail-to-rail input and output
single supply OpAmp, featuring low supply current of
50μA typical per amplifier, wide gain bandwidth
product of 1.7MHz and a slew rate of 0.8V/μs.
Furthermore, operating voltage from 2.2V single
supply can contribute to energy saving design, it is
most suitable for battery equipment required low
power.
Low input bias current makes NJU77552 suitable for
photodiode amplifiers, piezoelectric sensors, and
other applications with high-impedance applications.
A rail-to-rail input and output allows the device to be
used in wide variety of applications, such as high-
side current sensing, active filter, buffering and
others.
And also, High EMI immunity that can reduced
malfunctions caused by R
F
-noises from mobile
phones and other electronic devices, and input
tolerant that allows the input voltage
(Recommended: V
-
+5.5V) that exceed positive
supply voltage is ideal for robust applications.
The NJU77552 is available in 8-pin MSOP (VSP):
meet JEDEC MO-187-DA type package.
