We recently spoke with Jessica Engel from Harwin talked to us a bit about some new developments in power connector technology. One such development was the Datamate Mix-Tek series of power connectors. She says they’re lightweight, compact, offer or 20 and 40-A options, and provide a lot of design flexibility. You have the option to […]

Dual, simultaneous sampling, 14‑bit SAR ADC offers differential inputs
The AD7381 is a 14‑bit, pin-compatible, dual simultaneous sampling, high speed, low power, successive approximation register (SAR) analog-to-digital converter (ADC) that operates from a 3.0 V to 3.6 V power supply and features throughput rates up to 4 MSPS. The analog input type is differential, accepts a wide common-mode input voltage, and is sampled and […]
Teardown: Simple approach characterizes modern LED bulbs
LED bulbs we examined are often simpler than those made four years ago, sometimes employing discrete transistors to handle tasks once done via chips. Leland Teschler, Executive Editor Back in 2015, we examined LED bulbs putting out the equivalent of 60-W incandescent bulbs. We recently obtained several new LED bulbs to see how things have […]
