XR-7000

ADVANCE INFORMATION XR·7000 Log Vide«J) Amp~nfnelt" GENERAL DESCRIPTION The XR-7000 is a universal logarithmic video amplifier chip. Because of its extremely wide bandwidth, it can be used in systems ranging from audio applications to radar subsystems. The XR-7000 utilizes seven separate precision logarithmic elements. These elements may be used separately for small dynamic ranges or cascaded to offer an extremely wide dynamic range of operation. The XR-7000 has an internal band-gap voltage reference, a differential video summing amplifier, and a precision die temperature sensor, to aid in its system interfacing. Also included are internal power supply regulators to provide excellent power supply rejection. The XR-7000 is available in a 40-Pin ceramic or plastic package. It is designed to operate from dual 11 to 15 volt power supplies FUNCTIONAL BLOCK DIAGRAM FEATURES Seven Uncommitted Logging Elements Internal Band-Gap Voltage Reference Dual Tracking Regulators On-Board Precisio...
