STの低入力バイアス電流オペアンプは、オペアンプの入力側において電流または電圧のわずかな差を正確に測定する必要があるアプリケーションに最適です。低入力バイアス電流オペアンプは、フォトダイオード、pH計、およびその他の電位計などのアプリケーションにおいて、信号処理回路とセンサのインタフェースにおいて欠かせません。

STは、小信号シグナル・コンディショニング・アプリケーションに最適な低入力 / 超低入力バイアス電流を特徴とする幅広いオペアンプを提供しています。

High bandwidth Chopper Op Amps for automotive and industrial applications

Featuring very high-accuracy and stability (VIO ≤ 25 µV at 25 °C), our TSZ18 series of 5 V zero-drift op amps are ideal for high-accuracy, high-bandwidth sensor interfaces including body-signal monitors, blood-glucose meters, industrial sensors, factory automation, and low-side current sensing. Available in single-channel TSZ181 (1.2 x 1.3 mm DFN6 package) and dual-channel TSZ182 (2 x 2 mm DFN8 package) versions.

With an extended operating range of –40 to +150°C, the TSZ182H is ideal for harsh automotive environments.

TSV7 series: excellent precision (200 µV), low-power (10 µA or 60 µA)

The TSV711, TSV712, TSV714, TSV731, TSV732, TSV734 series of single-, dual-, and quad-channel operational amplifiers offers low-voltage operation (1.5 to 5.5 V), rail-to-rail inputs and outputs, and an excellent accuracy (V IO lower than 200 μV at 25 °C). Housed in the smallest industrial packages, these low-power devices benefit from ST’s 5 V CMOS technology and offer an excellent speed/power consumption ratio associated with an ultra-low input bias current. These characteristics make the TSV7 series ideal for sensor interfaces and active filtering for battery-powered applications in the wearable, portable consumer, medical and industrial segments.

TSV52 micropower amplifiers feature a high merit factor

ST's TSV521, TSV522, TSV524 are single, dual, and quad rail-to-rail input and output single-supply amplifiers operating from 2.7 to 5.5 V and featuring a very low supply current per amplifier of 45 µA while providing a 1.15 MHz bandwidth. The TSV52 family provides upgraded performance relative to ST‘s general-purpose range of standard op amps for a variety of applications, for example, in the industrial, medical and consumer segments.
