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...
