A precise, temperature-compensated voltage reference circuit lies at the heart of every analog-to-digital converter. Voltage-reference technology hadn't changed fundamentally in decades until last ...

Editor’s note: Battery charging in a float or maintenance mode has been around for a while, especially for standby power, emergency lighting, telecom, uninterruptible power, and other critical power ...

Measuring a floating dc voltage using a microcontroller’s analog-to-digital converter (ADC), with the dc+ to dc– ranging from 2.5 to 30 V and the low side able to float as high as 120 V above logic ...

A few years ago, I was working on the design of a data acquisition system (DAS) that would eventually need to be tested when manufactured. It had both high-side current sensing and floating diff-amp ...
