意法半导体的低输入偏置电流运算放大器完美适合那些需要准确测量运算放大器输入端较小的电流或电压差异的应用。在光电二极管、pH计或其他类似静电计的功能中,它们是将下游电子器件与传感器连在一起的关键要素。

意法半导体提供大量的低输入偏置电流运算放大器和超低输入偏置电流运算放大器,适合此类小信号调理范围的应用。

New high temperature (150°C), very high accuracy op amp for Automotive applications

Offering a very low offset voltage, an excellent speed/current consumption ratio, and 3 MHz gain bandwidth, the low-power, zero-drift TSZ181H operational amplifier is available in space-saving packages. Able to operate over an extended temperature range of -40 to +150°C, this miniature, ultra-precision and low quiescent current op amp is an ideal choice for high-accuracy, high-bandwidth sensor interfaces in automotive environment.

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, TSZ181H and TSZ182H are 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.

High bandwidth, low offset rail-to-rail Op Amps for Industrial and Automotive

Our new TSV791 and  TSV792 operational amplifiers offer a high gain-bandwidth product (GBW) of 50 MHz combined with excellent accuracy, which is provided by a maximum input voltage of 200 µV. This ensures high accuracy when amplifying small-amplitude input signals.

 

The TSV791 (single), TSV792 (dual) are also available in a SOT23-5 and Mini SO-8 package and can operate from 2.2 to 5.5 V in single supply. Fully specified on a 22 pF load and able to handle an output capacitor up to 1 nF, this Op Amps can also be used as an A/D converter input buffer.

Automotive grade version is also available both for TSV791 and TSV792.
