两路25μV微功耗运算放大器采用3mm×3mm封装

资料介绍
宽输入电压范围的传统的单芯片微功耗运算放大器需要大的散热面积、大封装和引脚。LT6011双路运算放大器可在一小型3mm×3mm DFN封装中实现25μV输入精度,微功耗工作,2.7V至36V输入电压范围。

Introduction The LT1790-1.25 micropower reference provides a stable
Conventional monolithic micropower op amps with a 1.25V reference voltage. The 7.87k:100k resistive ladder
