Hello everyone.
There is a friend asked me to help him to search an amplifier IC using DC voltage (as 0~10Vdc or -10Vdc~0V or similar) to control the AC output (audio signal as 100dB including negative and positive voltage) or a product with the IC function and already including the control components and software, it means that the board could using DAC to generates the 0~10Vdc to control it from computer DAC card or an independent unit, if only the IC then my friend could ask someone to help him to write the program, both info are welcome, and let my friend to decide it, thank you for your help.
Edit : The AC signal is as an normal audio signal.
