General Description

The NJU7046/NJU7047/NJU7048 are rail to rail input and output single supply operational amplifier featuring high speed and low input bias current. 9V/us slew rate, 5MHz gain bandwidth, 1pA input bias current and -40 to 125°C operating temperature range, make these amplifiers useful in wide variety of applications such as filters, integrators, current sensing, photodiode amplifiers and industrial applications. The rail-to-rail input and output enables designers to buffers of input and output for ADC, DAC, ASIC and other wide output swing devices. The NJU7046/NJU7047/NJU7048 operates in single supply 2.7V to 5.5V, and input common-mode voltage range includes the supply rails. Output voltage typically swings to within 70mV of the supply rails with 600Ω load, and 110mA short-circuit current drive capability. The NJU7046/NJU7047/NJU7048 are high RF-immunity to reduce malfunctions caused by RF noises from mobile phones and others. The NJU7046 is available in 5-pin SC-88A and SOT-23 package. NJU7047 is available in 8-pin SOP:JEDEC 150 mil, MSOP(TVSP): meet JEDEC MO-187-DA / thin and DFN that is thin and 2mm square small package. NJU7048 is available in 14-pin SOP and SSOP package.
