NJU7046
9V/μs High-Speed, Rail-to-rail I/O CMOS Operational Amplifier

  • Consumer
  • PLP
  • RoHS

The NJU7046 are rail to rail input and output single supply operational amplifier featuring high speed and low input bias current.

9V/µs 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.

As the rail-to-rail input and output can guarantee dynamic range to the maximum by power source voltage, it is the most optimal for buffers of input and output for ADC, DAC, ASIC and other wide output swing devices.

The NJU7046 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 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.
