 So, good morning everyone. My name is Piercarlo Cimonelli with ST Microelectronics. Welcome to IoT 2019. I'm a regional product marketing manager in charge of general purpose analog products. The demo we have today is a gas sensor where our CMOS zero drift operation amplifiers are used in a transimpedance configuration to convert a very small current coming from the sensor into a voltage. The voltage is then read by the analog to digital converter of a microcontroller and used to show the gas concentration on the screen. Precision operational amplifiers really are the primary link between the analog sensors and the digital world. The sensor that we're using is an electrochemical gas sensor that produces a very small current, just a few nanoamps per ppm of gas concentration. The reason we chose our TSU-111 operational amplifiers is that it's zero drift operational amplifiers that has a very low input bias current, about three orders of magnitude smaller than the current we are measuring. Another reason for the choice of TSU-111 is that this operational amplifier has a very low power consumption, 900 nanoamps at 25 degrees, which translates into a longer life for a remote battery powered sensor. ST zero drift operational amplifiers, TSU and TSU series are the best devices in the market today with a combination of high accuracy and very low current consumption. The ideal combination for signal conditioning in remote battery powered sensors. For more information, please visit ST.com and thanks for listening.
