Popular applications like LED lighting, brushless motors and power monitoring all require a combination of direct offline power electronics with isolated control electronics. Now more than ever, isolation is necessary in these designs.
An isolated operational amplifier (op amp) is too expensive for most of these high-volume applications. Digital isolation is more cost-effective, but typically requires an analog-to-digital converter (ADC) and multiple digital isolators.
Michael Score, FAE and senior member of TI’s technical staff, discusses a cost-optimized solution for moving analog across the isolation barrier in his newest article. Read it on EDN’s website now, and check out a sneak peek of Michael’s proposed solution in the schematic below.
