    No headroom, no problem: buffering and filtering an audio signal chain in low-voltage systems

    A high-fidelity audio signal chain gains several advantages when the system supply voltages are higher – the signal-to-noise ratio, dynamic range and slew rates can all improve with increasing supply voltages. But constraints from battery- and ...

    Can your RS-485 communication survive the great outdoors?

    RS-485 transceivers are designed to withstand harsh environments. In addition to noisy factory environments, this means RS-485 transceivers must also be robust enough to operate outdoors, where communication can be affected by voltage surge events, such as lightning strikes. So, how do you know if your RS-485 communication is capable of surviving...

    How to design for precision RTD measurements with ADCs

    In theory, temperature measurements using resistance temperature detectors (RTDs) should be simple: measure a temperature with an RTD that changes resistance with temperature, measure the resistance of the RTD, and convert that resistance to temperature through an equation or look-up table. What could possibly go wrong? Many design considerations...

    The need for current sensing in optical modules for 100G and beyond

    Industry pundits have recently speculated that demand for 100G/400G switches may take off in 2019, prompting optical transceiver module vendors to sample data center switches with high data transmission rates earlier than expected. As data center operators accelerate upgrades in preparation for 5G, demand for 100G/400G transceiver modules will become...

    What’s with chirping smoke detectors?

    Most homeowners and apartment dwellers can relate to being woken up in the middle of the night by a chirping smoke detector that needs a new battery. Usually, the smoke detector is installed in a hard-to-access location, so silencing the alarm involves engaging in acrobatics with a broomstick or some other similar object. Why do smoke detector batteries...
