BA3530FS - Rohm

BA3530FS Headphone amplifier with internal LPF and EVR for CD-ROM

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

Features

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.
