3.2W单声道D类音频功率放大器6 dB增益和自动短路恢复 3.2W Mono Class-D Audio Power Amplifier With 6-dB Gain and Auto Short-Circuit Recovery
The TPA2037D1 is a 3.2 W high efficiency filter-free class-D audio power amplifier class-D amp with 6 dB of fixed gain in a 1.21 mm × 1.16 mm wafer chip scale package WCSP. The device requires only one external component.
Features like 95% efficiency, 1.5 mA quiescent current, 0.1 µA shutdown current, 81-dB PSRR, 20 µV output noise, and improved RF immunity make the TPA2037D1 class-D amplifier ideal for cellular handsets. A start-up time of 4 ms with no audible pop makes the TPA2037D1 ideal for PDA and smart-phone applications.
