TSX7 series: high-precision low-power 16 V CMOS op amps
30 MHz-bandwidth unity-gain-stable amplifiers for Automotive and Industrial power management systems
STMicroelectronics enlarges its 5 V family portfolio with the TSV781 and the TSV782, respectively single and dual high-performance operational amplifiers.
The low input offset voltage and the slew rate of 20 V/µs make the devices ideal for low-side current measurement in power conversion systems, such as solar panels, telecom infrastructure or computer servers. The accurate measurement of current is the first and mandatory step for smart and efficient power conversion.
With high bandwidth and pico-Ampere input bias current, the TSV781 and the TSV782 are also well suited for photodiode signal conditioning in a transimpedance amplifier circuit. This application is useful in high performance UV sensors, smoke detectors or particle sensors.
Automotive grade qualified and available in SOT23-5L, SO-8 and MiniSO-8 tiny packages, the devices are the perfect choice for power management in HEV and EV systems, thanks to their very high accuracy.
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.
