... How to use the LA1265 1. LED lighting, muting drive output, stop signal (SD). • For LED lighting, muting drive output, stop signal, the output at pin 8 is used. • The voltage on pin 8, when tuned, turns from "H" to "L". (Active-Low) • Signal bandwidth at pin 8. − For AM, the bandwidth depends on the CF (BFU450CN) at pin 11 ...
