NJU77701
Wide-Band,High-Speed,Low-Offset,Low-Noise
Rail-to-Rail Input/Output CMOS Operational Amplifier
■GENERAL DESCRIPTION
The NJU77701 are Rail-to-Rail input/output CMOS single/dual/quad operational amplifiers.
They feature wide-band, high-speed, low-input-offset voltage and low-noise.
The NJU77701 has a high-speed characteristic of gain bandwidth 34MHz and slew rate 35V/µs.
Moreover, the NJU77701 achieves temperature fluctuations low offset and low noise characteristic. 6nV/
√Hz typ. at f=1kHz.
Therefore, the NJU77701 devices easily offer various sensing applications that require high speed and
accuracy. With their rail-to-rail output characteristic and 600-ohm load driving, these devices are able to
secure wide dynamic range for various applications.

(1) Differential voltage is the voltage difference between +INPUT and -INPUT.
For supply voltage less than +7V, the absolute maximum rating is equal to the supply voltage.
(2) The normal operation will establish when any input is within the Common Mode Input Voltage Range of electrical characteristics.
(3) EIA/JEDEC STANDARD Test board (76.2 x 114.3 x 1.6mm, FR-4) mounting.
Do not exceed “Power dissipation: PD” in which power dissipation in IC is shown by the absolute maximum rating.
See Figure1 “Power Dissipation Curve” when ambient temperature is over 25˚C .
