Pulse Width Modulation (PWM) drive amplifiers are referred to as class D amplifiers. To be clear the D does not denote digital as PWM drives may have characteristics of both digital and analog devices with respect to electronic signals. PWM drives typically have a smaller footprint, a primary advantage, but are inherently more complex in their electronic pulse, requiring more detailed set-up than analog drives or digital drives.
