The TPA2100P1 (sometimes called the TPA2100) is a mono, Class D converter and audio power amplifier designed with integrated DC-DC piezo speakers. The TPA2100P1 (TPA2100) is N capable of horning 2.5 volts, 19_VPeak-to-peak (6.7_voltRMS) from the power supply less than 1 to drive ceramic/piezoelectric % THD+

The DC-DC converter operates at a fixed frequency of 1.2 MHz. This TPA2100P1 (TPA2100) DC-DC converter provides a 10 V supply with a minimum number of external components. The DC-DC converter can be used to drive, which requires a 10 V supply voltage (note: the audio signal must be the normal function of the current boost converter).

This TPA2100P1 (TPA2100) features an integrated audio low-pass filter, high-frequency noise rejection (band and RF noise outside the codec), thus improving audio fidelity.
