The 3-channel audio power amplifier ICTA18H circuit
The IC working voltage is 10-30V. The limit output power is 50W(when the power supply is 20V and the impedance of the loudspeaker is 8Ω, there is 6W output power without any distortion). Figure 1 is the typical application of TA8218H. In the affiliated table are the pin functions and the tested data on Toshiba 2938XP(with Hangzhou U-201 multimeter, the R*100 gear). By the way, either of TA8218AH or TA8218AN can replace TA8218H.Figure 1. the typical application of TA8218H
