ZA2030
AAMTM 30W Class-D Bridged Audio Amplifier
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.
