Optical disc ICs Headphone amplifier with internal LPF and EVR for CD-ROM BA3530FS 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.
