... How to use LA1266 1. LED driver, muting drive output, stop signal (SD). • For LED drive, muting drive output, stop signal, the output at pin 8 is used. • 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 C.F (BFU450CN) at pin 14 capacitor is connected in place of the C.F, the bandwidth will get wider. − ...
