Overview:
Audio Power Amplifier with Built-in AGC AN12972A Increasing volume settings when using small speakers results in distortion as the output signal distorts at high gain settings. The AN12972A audio power amplifier features built-in automatic gain control (AGC) circuitry to minimize distortion by decreasing too high an input gain level. Using a low-noise amp minimizes noise even when the speaker is placed close to an ear.
Features:
- Built-in AGC circuitry if an input level is too high, the AGC is activated to minimize distortion, raising the overall volume level and reducing noise.
- Low noise amplifier.
- Input circuit format accommodates different input signals (mixing possible)
- Standby and speaker mute functions.
- Small package.
- Cellular phones, PDAs and other mobile equipment
