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

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.
