| AAM General Description The ZA2030 is a fully integrated 30W bridged Class-D Audio Amplifier. This simple, low-cost amplifier exhibits the high fidelity of a Class-A/B amplifier at very high efficiencies. The circuit is based on the proprietary variable frequency topology Analog Adaptive Modulation (AAM, Patent pending) that delivers excellent PSRR, fast response time and operates over a wide supply voltage range.
