【应用】小封装双运放SGM8302应用于高速数据采集保持电路设计
随着雷达,通信,遥感遥测,医学成像,精确控制等技术应用领域的不断发展,电子系统需要处理的模拟信号带宽以及动态范围越来越大,对数据采集系统的采集精度,采集速率等提出了更高要求。本文推荐SGMICRO的SGM8302高速运放作为高速数据采集保持电路,该运放实现100MHz-3dB带宽和12V的输入信号动态范围。
图1.数据采集保持电路
如图1所示,越来越多的设计应用领域要求具有高精度的A/D转换和实时处理功能。而A/D转换前端的采样保持电路直接关系到A/D芯片的转换速度和精度。为实现高速,高精度的A/D转换,也要求有高速的采样保持电路为A/D芯片做采样前的信号处理,做到尽可能快速地采样到信号,并尽可能长时间地保持住信号电平值。
采样保持电路能够跟踪或者保持输入模拟信号电平值,在理想状态下,当处于采样状态时,采样保持电路的输出信号跟随输入信号变化而变化;当处于保持状态时,采样保持电路的输出信号保持为接到保持命令的瞬间的输入信号电平值。
采样保持电路采用两级高精度运放组成,因运放的输入高阻抗特性,两级运放都起到信号隔离作用,他们就像两个电压跟随电路。前级隔离模拟输入信号,后级隔离A/D电路。两级运放中间采用小电容充放电电路实现实时数据保持。理想的高速A/D就需要高速高精度的采样保持电路,要求运放具有高速信号切换能力,并具有很低的输入零漂及温漂,以获得高精度。
图2.SGM8302架构
SGM8302是高速轨到轨输出的双运放,提供绿色环保的SOIC-8和MSOP-8封装。其主要特点如下:
1. 宽信号特性:4.5V-12V的单电源供电,及±2.25到±6V的双电源供电。电源范围也是输入/输出信号范围,所以SGM8302具有很宽的模拟输入信号范围。
2. 高速特性:100MHz的3dB带宽,并在56MHz带宽内增益平坦度达到0.1dB,信号摆率达到:155V/μs 。
3. 高精度:典型输入零漂为5 mv,输入温漂为12μV/°C。差分增益误差为0.02%,差分相位误差为0.02°。
4. 输出驱动电流达103mA,有利于A/D接入的信号稳定;
5. 工作温度范围为-40℃~+85℃,适合各种工业环境。
从上述特性可见,小封装双运放SGM8302的高速,高精度性能非常适合50MHz-100MHz的高速A/D的信号采样和保持电路设计。

SGM8051/2/3/4/5系列高速运算放大器应用指南与典型电路
本篇介绍了应用圣邦微电子高速运算放大器SGM805x系列的关键问题:(1)电压反馈型运放的闭环增益和闭环带宽的乘积为常数;(2)驱动容性负载时,在输出和负载间串联小电阻或减小反馈环路的带宽;(3)电源引脚应加去耦电容,版图布局走线应尽量减小寄生电容;(4)接地平面宽度足够,电流回路尽量短;(5)输入和输出信号线不应平行;(6)典型应用电路有差分放大器、有源滤波器和视频驱动器。
