SGM89000 概述
SGM89000 是一个2Vrms的流行/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。
SGM89000 能够驱动2Vrms的成2.5kΩ负载,3.3V电源电压。SGM89000 具有差分输入,并使用支持±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。SGM89000 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2Vrms的输出方法使用在音频产品的SGM89000 可以减少元件数量。所述SGM89000 不需要电源大于3.3V更大,以产生一个5.6VPP输出,也不会在装置需要一个分离轨电源。所述SGM89000 集成了电荷泵来产生一个负供电线,SGM89000 提供一个干净的,流行/点击 - 自由接地偏置2Vrms的输出。
SGM89000 是绿色TSSOP-14封装。它可在-40℃至+ 85℃的环境温度范围内。
SGM89000 GENERAL DESCRIPTION
The SGM89000 is a 2Vrms 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 SGM89000 is capable of driving 2Vrms into a 2.5kΩ load with 3.3V supply voltage. The device has differential inputs 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's and SOC converters. The SGM89000 has build-in shutdown control for pop/click-free on/off control.
Using the SGM89000 in audio products can reduce component count compared to traditional methods of generating a 2Vrms output. The SGM89000 doesn't require a power supply greater than 3.3V to generate a 5.6VPP output, nor does the device require a split rail power supply. The SGM89000 integrates a charge pump to generate a negative supply rail that provides a clean, pop/click-free ground-biased 2Vrms output.
The SGM89000 is available in Green TSSOP-14 package. It operates over an ambient temperature range of -40℃ to +85℃.
