资 源 简 介
This device is a monolithic two-stage high-frequency amplifier with differenTIal inputs and outputs.
Internal feedback provides wide bandwidth, low phase distorTIon, and excellent gain stability. Variable gain based on signal summaTIon provides large AGC control over a wide bandwidth with low harmonic distorTIon. Emitter-follower outputs enable the device to drive capacitive loads. All stages are current-source biased to obtain high common-mode and supply-voltage rejection ratios. The gain may be electronically attenuated by applying a control voltage to the AGC pin. No external compensation components are required.
This device is particularly useful in TV and radio IF and RF AGC circuits, as well as magnetic-tape and disk-file systems where AGC is needed.
