NJM2719
Low Noise, High-Speed Dual Operational Amplifier
■ GENERAL 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).
