NJU7664 Datasheet | New Japan Radio

.. VOLTAGE CONVERTER FOR GaAs FET - GENERAL DESCRIPTION The NJU7664 is a voltage converter for GaAs FET, which contains CR oscillation circuit and dual operational amplifiers. The voltage converter is a circuit operated by the charge pumping system, and it generates the negative voltage from the positive power supply. Furthermore the charge pumping capacitor is incorporated. Both of two operational amplifiers with the gain resistance which is set up at -OdB output the negative voltage by the inverted input voltage. The NJU7664 realizes to operate the GaAs FET requiring the negative gate biassing. - PACKAGE OUTLINE PRELIMINARY NJU7664R - Features - Voltage...
