EL driver for portable sets
BA3899F
The BA3899F is an IC developed for EL drive applications. It uses a more compact interface than transformer sys-
tems, and is ideal for use in thin sets.
•Applications
Pagers, electronic notebooks and other portable devices
•Features
1) Drive oscillation frequency can be set using external capacitance.
2) Equipped with standby control pin.
•Absolute maximum ratings (Ta = 25°C)
