Application Notes
- Multi-Device Configuration for TPA32xx AmplifiersPDF, 102 Kb, File published: Sep 27, 2017
The TPA324x and TPA325x family of parts (TPA3244, TPA3245, TPA3250, TPA3251, and TPA3255)comes equipped with functionality to simplify systems with multiple Class-D amplifiers. Class-D amplifiersuse pulse-width modulation (PWM) switching (450 kHz – 600 kHz), which are discrete packets of energy,to deliver large amounts of power with very high efficiency. However, issues can arise if multiple
