TPA2039D1中文资料具有 12dB 固定增益和短路保护的 3.2W 单声道模拟输入 D 类音频放大器数据手册TI规格书

描述 Description

The TPA2039D1 is a 3.2 W high efficiency filter-free class-D audio power amplifier (class-D amp) with 12 dB of fixed gain in a tiny 1.21 mm × 1.16 mm wafer chip scale package (WCSP). The device requires only one external component. Features like 93% efficiency, 1.5 mA quiescent current, 0.1 µA shutdown current, 82-dB PSRR, 27 µV output noise and improved RF immunity make the TPA2039D1 class-D amplifier ideal for cellular handsets. A fast start-up time of 4 ms with no audible pop makes the TPA2039D1 ideal for PDA and smart-phone applications.
