Analog is critical to ensuring IoT products are robust and reliable.

The analog side of the Internet of Things (IoT) has always existed. In recent years, however, design engineers realized its importance in making IoT systems robust and reliable.

In the past, IoT engineers mainly focused on the digital side of the IoT. That is, until they discovered that if the processor or microcontroller don't have the right information from the sensor front-end, any decisions made wouldn't be accurate because of wrong assumptions derived by a poorly designed analog front-end.

In other words, decisions within the signal chain path are of relevance and in accordance with what is occurring in the environment. As a result, it's vital to have a low-noise signal chain that can read and accurately interpret data from a sensing element.

In this case, design engineers need accurate, low-noise, precise and high-speed ICs to design reliable and robust IoT systems that can sense the real world and take or suggest decisions that will avoid issues like equipment failures, potentially increasing the overall efficiency in buildings, factories and more.

New analog ICs, such as sensors, amplifiers and analog-to-digital converters (ADCs), are now designed to meet such requirements and improve IoT systems, according to Giovanni Campanella, general manager for building automation at Texas Instruments. He asserted that innovation is occurring at the same pace on both the analog and digital sides.
