TSX7 series

TSX7 series: High-Precision Low-Power 16V CMOS Op Amps

The TSX711, TSX712, and TSX719x offer low power consumption and exhibit an offset voltage less than 200µV. Rail-to-rail input and output functions, associated with an extended power supply range from 2.7V to 16V, allows the TSX711 to be used on a wide range of applications. The TSX711 perfectly fits automotive requirements. It has a -40°C to +125°C temperature range and ability to sustain 4kV ESD. Also available in a tiny SOT-23 package.

Op-amps for CO detector

Unmonitored carbon monoxide (CO) gas can rapidly become a danger. Consequently, monitoring air quality is mandatory for security reasons in many industries.

ST's TSU101, TSU102, TSU104 nanopower amplifiers, TSV711, TSV731 high-precision op-amps, and TSZ121 chopper amplifier take into account bias voltage and polarity variations and help ensure the best sensitivity in 2- and 3-electrode gas sensors.

Moreover, their low supply voltage and ultralow power consumption, while delivering almost no current, make them a perfect fit for handheld safety detectors operating in toxic environments.
