Other Parts Discussed in Post: TLV333 , TLV2333 , TLV4333 Many sensors produce low-level DC outputs that require a high input-impedance amplification stage to increase the signal amplitude. Sensors used in personal and portable electronics require operational…
Other Parts Discussed in Post: TLV369 , TLV379 In portable electronics designs, typical battery-monitoring systems measure battery voltage and battery current to detect when the battery needs charging or replacement. In this post, I’ll demonstrate battery…

High-precision data-acquisition systems are designed to minimize errors from various system components, like those introduced by switching transients on the reference input of a data converter. In…
Other Parts Discussed in Post: TPS62840 多くのバッテリ駆動アプリケーションでは、バッテリ電圧が最小になった場合でもバッテリ駆動時間を延ばすため、降圧型コンバータを、V IN がV OUT に近い100%のデューティ・サイクルで動作させることが必要になります。
例えば、スマート・メータに給電する2本の二酸化マンガン・リチウム(Li-MnO 2 )電池は、充電不可の一次電池で、リチウム塩化チオニル電池より安価な一方、動作寿命が長期(最長20年)であるため…
