Part Details:

Dual 260 MHz a Gain = +2.0 & +2.2 Buffer AD8079 FEATURES FUNCTIONAL BLOCK DIAGRAM Factory Set Gain 8-Pin Plastic SOIC AD8079A: Gain = +2.0 (Also +1.0 & ­1.0)AD8079B: Gain = +2.2 (Also +1 & ­1.2)Gain of 2.2 Compensates for System Gain Loss +IN1 1 8 OUT1 Minimizes External Components GND 2 7 +V Tight Control of Gain and Gain Matching (0.1%) S AD8079 Optimum Dual Pinout GND 3 6 ­VS Simplifies PCB Layout +IN2 4 5 OUT2 Low Crosstalk of ­70 dB @ 5 MHz Excellent Video Specifications (RL = 150 ) Gain Flatness 0.1 dB to 50 MHz0.01% Differential Gain Error cables and transformers. Its low distortion and fast settling are 0.02 Differential Phase Error ideal for buffering high speed dual or differential A-to-D con- Low Power of 50 mW/Amplifier (5 mA) verters. High Speed and Fast Settling The AD8079 features a unique transimpedance linearization 260 MHz, ­3 dB Bandwidth circuitry. This allows it to drive video loads with excellent differ- 750 V/ s Slew Rate (2 V Step), 800 V/ s (4 V Step) ential gain and phase performance of 0.01% and 0.02° on only 40 ns Settling Time to 0.1% (2 V Step) 50 mW of power per amplifier. It features gain flatness of 0.1 dB Low Distortion of ­65 dBc THD, fC = 5 MHz to 50 MHz. This makes the AD8079 ideal for professional video High Output Drive of Over 70 mA electronics such as cameras and video switchers. Drives Up to 8 Back-Terminated 75 Loads (4 Loads/ Side) While Maintaining Good Differential Gain/ The AD8079 offers low power of 5 mA/amplifier (VS = ± 5 V) Phase Performance (0.01%/0.17 )
