reduce overshoot when EN 1 or EN 2 are activated with 0 a long inductive ground wire. VS = ±12V RL = 100Ω 5. The R, G and B amplifiers have slightly different –20 RF = RG = 1.6k RS = 10Ω frequency responses due to different output trace routing to R –40 G F (between pins 3 and 4). All amplifiers have slightly less bandwidth in PCB #039 than when –60 B measured alone as shown in the Typical AC Perfor- mance table. R ALL HOSTILE CROSSTALK (dB) –80 6. Part-to-part variation can change the peaking by ±0.25dB. –100 1 10 100 FREQUENCY (MHz)
