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.
