Guidelines for Measuring Audio Power Amplifier Performance
PDF, 765 Kb, File published: Oct 30, 2001
This application note provides guidelines for measuring the date sheet parameters of Texas Instruments audio power amplifiers (APAs) using prefabricated evaluation modules (EVMs). The primary equipment used for the measurements consists of the System Two audio measurement system by Audio Precision , a digital multimeter (DMM), and a dc power supply.

Series: TPA731 (7)
