TPA2039D1

固定增益 3.2W 单声道 D 类，具有集成 DAC 噪声滤波器

The 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.
