Low-current audio headphone driver
BA3574BFS
The BA3574BFS is a headphone driver with a fixed-gain bass boost circuit and an AVC circuit that keeps the output
below a fixed level. It features low current dissipation, and low output noise, and is ideal for use in portable digital audio
equipment.
FApplications
Portable CD and MD players
FFeatures
1) Low current dissipation (when V
CC
= 2.4V, the quies-
cent current is 4.9mA).
2) Suitable for use in digital audio equipment (voltage
gain: G
V
= 11.8dB, output noise voltage: V
NO
=
*102dBm
typ.).
3) Bass boost circuit.
4) AVC (Auto Volume Control) circuit, for output limiting.
5) Standby switch.
6) Mute switch.
7) Ripple filter.
8) No output coupling capacitor required.
9) Beep circuit.
10) SSOP-A20 package.
