意法半导体’的低输入偏置电流运算放大器特别适于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。 低输入偏置电流运算放大器对于在以下应用中连接下游电子和传感器至关重要:光电二极管、pH计和其它功能与静电计类似的器件。

意法半导体拥有很多适于小信号调节应用的精密运算放大器。

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, the TSZ182H is ideal for harsh automotive environments.

高带宽、低偏移的轨到轨运算放大器,面向工业和汽车应用

新款TSV7292和TSV792IY运算放大器最大输入电压为200µV,可提供50 MHz的高增益带宽积(GBW)和极高的精度。这就保证了在放大小振幅输入信号时的高精度

 

TSV792和TSV792IY还采用微型SO-8封装,单一电源供电,可在2.2至5.5 V电压范围内运行。该运算放大器完全指定在22 pF负载,能够处理的输出电容可达1 nF,也可用作A/D转换器输入缓冲区

 

 

 

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.
