BH7881EFV - Stereo Speaker / Headphone Amplifier

Datasheet Summary

Description

The BH7881EFV is a low voltage, low noise, high output speaker/headphone amplifier IC, in which a Bi-CMOS process is used.

An on-chip speaker amplifier circuit that is capable of 2W+2W output can be used as a headphone amplifier by switching the operating mode.

Features

  • 1) Built-in low saturation type regulator (Digital power supply driver, voltage and current variable, short circuit detection) 2) Bass boost mode, gain switching functions 3) Speaker MUTE function (Headphone mode) 4) Built-in line amplifier output (gain adjustment, LPF setting) active/suspend function (TTL input control pin) 5) Hysteretic thermal shutdown function (Set for approximately 150℃ /90℃) 6) IC protection function (SP pin VCC/GND short circuit detection) 7) Speaker protection function.

Class-AB Speaker Amplifiers 2W + 2W Stereo Speaker / Headphone Amplifier BH7881EFV No.10077EAT05 ●Description The BH7881EFV is a low voltage, low noise, high output speaker/headphone amplifier IC, in which a Bi-CMOS process is used. An on-chip speaker amplifier circuit that is capable of 2W+2W output can be used as a headphone amplifier by switching the operating mode. This makes it possible to configure an audio system using few external devices. With a built-in, low saturation regulator with programmable output voltage and output current, clear tone quality is obtained even when directly connected to a digital power supply. A peripheral analog circuit can also be regulator driven.
