TPA2100P1YZHR 19Vpp mono class dd audio amplifier for piezoelectric/ceramic speakers

illustrate   The TPA2100P1 (sometimes called TPA2100) is a mono, Class D converter and audio power amplifier designed with integrated DC-DC piezo ceramic speakers. The TPA2100P1 (TPA2100) is capable of speaker 2.5 volts, 19 V peak (6.7 volt RMS) from less than 1 power supply to drive ceramic/piezo % THD+ The DC-DC converter operates at a fixed frequency of 1.2 MHz. The 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, requiring a 10 V supply voltage (note: the audio signal must be the normal function of the current boost converter) etc. The TPA2100P1 (TPA2100) features an integrated audio low-pass filter, high-frequency noise rejection (bands outside the codec and RF noise), resulting in improved audio fidelity.   characteristic   19 V peak-to-peak output voltage V supply load from 2.5 The integrated DC-DC converter produces a 10 V supply No external Schottky diode required Integrated audio input low-pass filter Small inductive boost converter The supply voltage range is from 2.5 V to 5.5 V Optional gain of 12 dB, 16 dB and 24 dB Separate boost converter, shutdown control and audio amplifier Fast boot time: 8 ms Low supply current: 5.5 mA Low shutdown current: "1 microampere."
