Description

The BH3540AFS is an H/P amplifier with internal secondary LPF and EVR circuits. When multibit output from a D/A converter BH3540AFS is input, the secondary LPF outputs an audio signal. 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.
