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。

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.

High bandwidth, low offset rail-to-rail Op Amp

The TSV792 operational amplifier offers 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 TSV792 is available in a 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 Amp can also be used as an A/D converter input buffer.

 

 

 

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.
