D7630 application circuit
Source: InternetPublisher:刘德华河北分华 Updated: 2011/06/10
D7630 is a dedicated integrated circuit with DC volume, tone and balance control functions. It has a strong control function and can be used as a volume, tone and channel balance control circuit for a two-channel audio power amplifier circuit. This circuit is generally controlled manually, and its control function is realized by adjusting the level of the DC control voltage through a potentiometer. If the manual potentiometer adjustment is replaced by a digital-to-analog conversion circuit, remote control operation of the control circuit can be achieved. Latest Control Circuits Circuits
