AN12960A
AN12960A
Monaural Class-D amplifier IC with built-in AGC
AGC circuit which prevents sound distortion due to output saturation caused by excessive input is embedded. This IC is equipped with
Auto SP Save function which automatically detects non-signal input condition and stops speaker amplifier, and noise at non-signal input
can be reduced.
Either I
AN12960A is a Class-D audio amplifier IC for mobile devices such as mobile phone and so on.
1. High power efficiency by Class-D power amplifier (85%, 500 mW output power with 8 Ω load)
2. The original AGC circuit makes low distortion whether AGC is active or not.
3. Auto SP Save function
4. EVR (Electric volume) function
5. Gain Selection
6. I

The ON level and attack/recovery time of the AGC can be selected with I
In case of non-signal input, the auto SP save function automatically turns off speaker amplifier, and PWM output is stopped.
When larger input signal than set detection level is input, SP Save mode is automatically deactivated and speaker amplifier starts
and signal is output. The detection level and detection time for the function to be active are selectable.
