BA3577FS
The BA3577FS is a headphone driver developed for portable digital audio equipment that supports a voltage of 1.5V.
FApplications
Portable MD players and others
FFeatures
1) 1.5V supported.
2) Low current consumption
(At PO = 0.5mW / ch, VCC inflow current = 3.3mA, and
)B inflow current = 6.8mA (Typ.)).
3) Output coupling capacitor of 100µF produces fC =
45Hz (RL = 16Ω).
4) Internal muting switch.
5) Internal ripple filter.
6) Internal BEEP circuit.
FAbsolute maximum ratings (Ta = 25_C)
