NJU7755x Rail-to-Rail I/O Op-Amps Nisshinbo NJU7755x Rail-to-Rail I/O Op-Amps are single/dual/quad input/output and single-supply operational amplifiers. These operational amplifiers offer 50µA low supply current per amplifier, 1.7MHz wide gain-bandwidth, and a 0.8V/µs slew rate. The NJU7755x amplifiers operate from a 1.8V single supply voltage that contributes to the energy-saving design and are suitable for low-power battery equipment. These amplifiers provide low input bias current and are used for photodiode amplifiers, piezoelectric sensors, smoke detectors, and high-impedance applications. Typical applications include audio amplifiers, high-side current sensing, active filters, and buffering.
