NJU7755x Series Operational Amplifier

Nisshinbo Micro Devices' NJU77550, NJU77551, NJU77552, and NJU77554 are single, dual, and quad rail-to-rail input and output single-supply op amps featuring low supply current of 50 µA (typical) per amplifier, wide gain bandwidth of 1.7 MHz, and a slew rate of 0.8 V/µs. An operating voltage from 1.8 V single supply contributes to the energy-saving design. They are most suitable for battery equipment requiring low power. Low input bias current makes the NJU7755x series suitable for photodiode amplifiers, piezoelectric sensors, smoke detectors, and other applications with high-impedance applications. Rail-to-rail input and output allow the device to be used in a wide variety of applications, such as audio amplifiers, high-side current sensing, active filters, buffering, and others. High EMI immunity can reduce malfunctions caused by RF noise from mobile phones and other electronic devices, and overvoltage input protection that allows input voltage (recommended: V^-+5.5 V) that exceeds positive supply voltage is ideal for robust industrial applications. The NJU7755x series guarantees supply voltage of 1.8 V to 5.5 V from a single supply, making it ideal for low voltage applications. In addition, the operating temperature range is expanded to -55°C to +125°C, allowing the op amp to be used in harsh environments with large temperature changes. The NJU77550 and NJU77551 are available in 5-pin SC-88A and SOT-23-5 packages. The NJU77552 is available in the 8-pin SOP8, MSOP8 (TVSP8) (meet JEDEC MO-187-DA/thin type), and DFN8-U1 (ESON8-U1). The NJU77554 is available in an SSOP14 package.
