LT1259/LT1260
TYPICAL APPLICATIO S
4. Capacitors C1 and C6 are optional and only needed to
reduce overshoot when EN 1 or EN 2 are activated with
a long inductive ground wire.
5. The R, G and B amplifiers have slightly different
frequency responses due to different output trace
routing to RF (between pins 3 and 4). All amplifiers
have slightly less bandwidth in PCB #039 than when
measured alone as shown in the Typical AC Perfor-
mance table.
6. Part-to-part variation can change the peaking by
±0.25dB.
