BA3530FS
The BA3530FS is an H / P amplifier with internal secondary LPF and EVR circuits. When multibit output from a D / A
converter is input, the secondary LPF outputs an audio signal. The amplifier circuit allows for line output and headphone
output. The output level for headphones can be changed with the EVR circuit. This IC also has independent internal mute
circuits for the left and right channels.
FApplications
CD-ROM drives and other products (with line and headphone output pins) that process digital audio signals
FFeatures
1) Internal LPF, line amplifier and EVR.
2) Internal mute function.
3) Internal thermal shutdown circuit.
4) No attached components are needed for oscillation
prevention, even at a load of 8Ω.
5) Mute function reduces the popping noises that can
occur when the power is turned on and off.
