Low-current audio headphone driver

BA3575FS

The BA3575FS is a headphone driver with an AVC circuit that keeps the output below a fixed level. It features low current

consumption, and low output noise, and is ideal for use in portable digital audio equipment.

FApplications

Portable CD players

FFeatures

1) Low current consumption (when VCC = 2.4 V, the

quiescent current is 4.9mA).

2) Suitable for use in digital audio equipment (voltage

gain: GV = 11.8dB, output noise voltage: VNO =

–102dBm typ.).

3) ATT circuit (gain switch).

4) AVC (Auto Volume Control) circuit, for output limiting.

5) Internal standby switch.

6) Internal mute switch.

7) Internal ripple filter.

8) No output coupling capacitor required.

9) Internal beep circuit.

10) SSOP-A20 package.

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
