DESCRIPTION
The SN761643 is an automatic gain control (AGC) amplifier for the TV tuner system of a digital TV, CATV, or
STB. The circuit consists of three stages of controlled-gain amplification, followed by a fixed-gain output
amplifier.
The device is packaged in an 8-pin MSOP suitable for surface mounting.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
