Other Parts Discussed in Post: LM7301 Protecting expensive, critical or hard-to-repair equipment against overcurrent and power-supply fault conditions can be achieved with universally available operational amplifiers ( op amps ) and a few external components…
There are two types of voltage references, shunt references and series references. Each type has its own usage conditions and the process of selecting between the two can be intimidating. Comparison tables do exist, but they typically provide little insight…

最近は「ポータブルな将来」が目の前に迫っているという印象を受けます。以前は扱いが面倒でサイズが大きかった各種デバイスも、軽量化とポータブル化が進んできています。そのことを実感するのはパーソナル・エレクトロニクス分野です。初期の携帯電話は重く、通信速度も低速でしたが、現在のスマートフォンは薄型で高速であり、バッテリ動作時間も大幅に延長できています。
また、パーソナル・ヘルスケア (個人レベルの健康管理…
In this three-part series, I discussed the solutions for generating two well-matched, low-drift voltage references. We started with three topologies in Part 1 , we compared and contrasted the differences in terms of performance in Part 2 . Now, let’s…
In my previous post, we talked about three topologies for generating two high-accuracy voltage reference outputs . Today, we’ll compare the performance of these solutions from three perspectives: total error, drift tracking and matching between outputs…
In the last two posts in this series I talked about how to build 3-wire analog outputs and how to protect them from transient overstress . This post will finish off the discussion of 3-wire analog outputs with some solutions to one more application-specific…
In part two of our Understanding Voltage References series, my colleague Christopher Dean talked about ultra-low dropout and how it is not just for the series reference. Today I’ll address how to achieve shunt reference flexibility with series reference…
