Artificial Cooling A Tricky Topic for Climate Panel
It’s Plan B in the fight against climate change: cooling the planet by sucking heat-trapping CO2 from the air or reflecting sunlight back into space. Called geoengineering, it’s considered mad science by opponents. Supporters say it would be foolish to ignore it, since plan A — slashing carbon emissions from fossil fuels — is moving […]
Micropower 30-µV op amp settles in 15 µS to 0.0015 percent
Linear Technology (Milpitas, CA) introduced the LT6020, a dual 3-V to 30-V fast settling operational amplifier, featuring 30 µV maximum input offset voltage and 0.5 µV/°C max VOS drift. While supply current is only 100 µA maximum per amplifier, proprietary slew enhancement circuitry provides fast clean output step response. The LT6020 settles to 0.0015 percent […]
