General 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.
Key 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.
