DESCRIPTION

The NJU77806 is a single low noise rail-to-rail output

CMOS operational amplifier offer a low input voltage

noise density of 5.5nV/√Hz at 1kHz while consuming

only 500μA of supply current, and have wide gain

bandwidth of 4.4MHz and slew rate of 1.1V/μs. These

characteristics makes NJU77806 ideal when excellent

performance is required in low noise and low power

applications.

The very low noise of 5.5nV/√Hz at 1kHz and low 1/f

noise of 11nV/√Hz at 10Hz while consuming only

500μA of supply current, give the NJU77806 the wide

dynamic range necessary for preamps in microphones,

audio amplifiers, active filters and sensor amplifiers.

NJU77806 guaranteed from 1.8V to 5V

specifications. In addition to low noise and low supply

current, the NJU77806 operate on supplies as low as

1.8V. These features makes NJU77806 ideal for

battery powered applications.

The NJU77806 is high RF-immunity to reduce

malfunctions caused by RF noises from mobile phones

and others.

The NJU77806 is available in space saving 5-pin

SC-88A. The small package saves space on PC

boards, and enables the design of small portable

electronic devices.
