SGM8905概述
SGM8905是一个2Vrms的，以3Vrms弹出/点击免费立体声线路驱动器，旨在允许拆除隔直流电容器减少元件数量和成本的输出。该器件非常适用于单电源电子产品，大小和成本是关键设计参数。
SGM8905是能够驱动3Vrms成一个2.5kΩ负载5V电源电压。该器件具有单输入和使用支持±1V / V的增益范围为±10V / V外部增益设置电阻。使用外部增益电阻还允许一个2阶低通滤波器恭维DAC的和SOC转换器的实现。SGM8905具有内置的关断控制流行/点击免费开/关控制。
相比于传统的生成3Vrms输出的方法使用在音频产品的SGM8905可以减少元件数量。所述SGM8905不需要电源大于5V以产生8.5VPP输出，也不会在装置需要一个分离轨电源。所述SGM8905集成了电荷泵来产生一个负供电线，它提供一个干净的，流行/点击 - 自由接地偏置3Vrms输出。
SGM8905是绿色MSOP-10（裸露焊盘）封装。它可在-40℃至+ 85℃的环境温度范围内。
SGM8905 GENERAL DESCRIPTION
The SGM8905 is a 2Vrms to 3Vrms pop/click-free stereo line driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters.
The SGM8905 is capable of driving 3Vrms into a 2.5kΩ load with 5V supply voltage. The device has single input and uses external gain setting resistors that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd-order low pass filter to compliment DAC&＃39;s and SOC converters. The SGM8905 has build-in shutdown control for pop/click-free on/off control.
Using the SGM8905 in audio products can reduce component count compared to traditional methods of generating a 3Vrms output. The SGM8905 doesn&＃39;t require a power supply greater than 5V to generate an 8.5VPP output, nor does the device require a split rail power supply. The SGM8905 integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 3Vrms output.
The SGM8905 is available in Green MSOP-10 (Exposed Pad) package. It operates over an ambient temperature range of -40℃ to +85℃.
