Description

The NJU77550/NJU77551/NJU77552/NJU77554 are single, dual and quad 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 1.8V single supply can contribute to energy saving design, it is most suitable for battery equipment required low power. Low input bias current makes NJU7755x series suitable for photodiode amplifiers, piezoelectric sensors, smoke detector 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 audio amplifier, high-side current sensing, active filter, buffering and others. And also, High EMI immunity that can reduced malfunctions caused by RF-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 industrial applications. The NJU7755x series guarantees the specifications from 1.8V to 5.5V single supply, making it ideal for low voltage applications. In addition, the operating temperature is expanded to -55°C to 125°C, which can be used in harsh environments with large temperature changes. The NJU77550/NJU77551 is available in 5-pin SC-88A and SOT-23-5 package. The NJU77552 is available in 8-pin SOP8, MSOP (TVSP): meet JEDEC MO-187-DA / thin type package and DFN that is thin and 2mm square small package. The NJU77554 is available in SSOP14 package.
