NJM2719 Series
Low Noise,High-Speed Dual Operational Amplifier

Download Datasheet

  • Description

    The NJM2719 is a high speed voltage feedback dual operational amplifier specifically optimized for low voltage noise. Combining a voltage noise of 2.5nV/√Hz typ. (at f =100kHz) and unity gain of 100MHz, the NJM2719 is ideal for I/Q baseband amplifier, RFID reader application and other wireless communication system designs. The NJM2719 is available in two 8-lead package options: tiny fine pitch surface mount (SSOP/MSOP).
