Op-amps for CO detector
Unmonitored gas can rapidly become a danger. Consequently, monitoring air quality is mandatory for security reasons in many industries.
ST's op amps 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 ultra-low power consumption, while delivering almost no current, make them a perfect fit for handheld safety detectors operating in toxic environments.
