背景
智慧型手機和物聯網終端設備越來越趨向小型化,因此要求搭載的元件也要越來越小。另一方面,若要提高應用產品的控制能力,就需要高精度放大感測器的微小訊號,並在該前提下實現小型化。在此背景下ROHM透過進一步改善多年來累積的「電路設計技術」、「製程技術」、「封裝技術」,開發出同時滿足「小型化」和「高精度」等需求的運算放大器。
概要
造成運算放大器誤差的原因通常包括輸入偏移電壓和雜訊,兩者都是與放大精度相關的關鍵因素,可透過擴大內建電晶體尺寸得到抑制,然而卻也涉及到與小型化之間的取捨關係。透過嵌入利用ROHM獨家電路設計技術所開發出來的偏移電壓校正電路,本產品在保持電晶體尺寸不變的前提下,實現了最高僅1mV的低輸入偏移電壓。另外不僅利用ROHM獨家製程技術改善了常見的閃爍雜訊,還透過從元件層面重新調整電阻分量,實現了等效輸入雜訊電壓密度僅為12nV/√Hz的超低雜訊。此外新產品採用了WLCSP(Wafer Level Chip Size Package)封裝,該封裝利用ROHM獨家封裝技術,將引腳間距縮小到了0.3mm。與傳統產品相比,尺寸減小了約69%;與之前的小型產品相比,尺寸減小了約46%。

・智慧型手機、配備檢測放大器的小型物聯網設備等
