TPA2100P1 - Texas Instruments

TPA2100P1 Mono Class-D Audio Amplifier

The TPA2100P1 (sometimes referred to as TPA2100) is a mono, Class-D audio power amplifier with integrated DC-DC converter designed for piezo and ceramic speakers. The TPA2100P1 (TPA2100) is capable of driving a ceramic / piezo speaker with 19 VPP (6.7 VRMS) from a 2.5 V power supply at less than 1% THD+N. The DC-DC converter operates at a fixed frequency of .
