Furthermore, operating voltage from 1.8V single supply can contribute to energy saving design, it is most suitable for battery equipment required low power. ■ APPLICATIONS ● Battery-Powered Equipment - Audio, Healthcare, Security, etc. ● Gas / Smoke Sensors ● Smart Meter ● Sensor Interface ● Active Filters ● Photodiode Amplifier 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. 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 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.

For the input voltage 300mV below the negative supply  voltage, the ESD protection operates to protect the input  terminal. At this moment, the current flowing in protection  element is allowed up to 10 mA.

The definition of EMIRR is given by the following equation1. VRF_PEAK EMIRR=20∙log ൬ ൰ |∆VIO | --- eq.1 VRF_PEAK : RF Signal Amplitude [VP] ∆VIO : Input offset voltage shift quantity [V] The tolerance of the RF signal can be grasped by measuring an RF signal and offset voltage shift quantity. Offset voltage shift is small so that a value of EMIRR is big. And it understands that the tolerance for the RF signal is high. In addition, about the input offset voltage shift with the RF signal, there is the thinking that influence applied to the input terminal is dominant. Therefore, generally the EMIRR becomes value that applied an RF signal to +INPUT terminal.
