This IC consists of a two stage gain control amplifier and a fixed gain video amplifier. The device provides a differential input and differential output for noise performance, which eliminates shielding requirements. Stringent quality assurance and test procedures ensure the highest reliability and performance. 6 5 3221 The package is 8-pin SSOP (Shrink Small Outline Package) suitable for surface mount. This IC is manufactured using the 10 GHz f T NESAT AL silicon bipolar process. This process uses silicon nitride passivation film. This material can protect chip surface from external pollution and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability. 7 8 N 1 2 3 3.0 MAX 4 All dimensions are typical unless specified otherwise.
