【技术】斩波稳定运算放大器ISL28133的长期漂移特性测试
ISL28133运算放大器是Intersil(已被RENESAS收购)旗下的一款单通道、微功率的斩波稳定运算放大器,该运算放大器针对1.8V~5.5V的单电源工作进行了优化。ISL28133低至18μA电源电流和宽电压输入范围特性使其成为适用于各种应用的运算放大器。除此之外,ISL28133非常适合用于2节AA电池或单节锂离子电池供电的手持设备。其采用5 Ld SOT-23、5 Ld SC70和6 Ld的1.6mmx1.6mm μTDFN封装,所有器件均可在-40°C~125°C的温度范围内工作。本文主要介绍ISL28133运算放大器的长期漂移特性。
图1 长期漂移测试电路
图2展示了30个独立ISL28133放大器在25°C下连续572天的日VOS漂移测量值图。30个放大器单元以10k的增益进行连接(见图3),在单个PC板上安装并保持在室温下。在计算机控制下,DVM和扫描仪每天测量这30个放大器的输出。从初始VOS值中减去每日VOS测量值,以计算从零小时开始的VOS偏移。测试板则由UPS进行供电,以保持测试单元的不间断供电。在测试过程中,由于检测到测量扫描仪掉电而导致测量数据丢失的3个实例,其范围从2天到2周不等,并对数据进行插值。
图2 30个放大器单元的长期漂移(VOS vs 时间)特性
图3 单个放大器单元的长期漂移(VOS vs 时间)特性
最后,这30个放大器(见图2)在572天期间内放大器VOS的变化小于±100nV,而且数据中并无明显的VOS长期漂移趋势。其出色的长期漂移性能是斩波放大器测量和校正VOS误差的结果,这仅仅是由于外部元件在长期状态下稳定性发生变化而为VOS误差做出贡献。
