Low power radio standard simplifies sensor networks

Low power radio standard simplifies sensor networks

Multichannel time-synchronised mesh networks based on 802.15.4 radios address many of the challenges involved in designing wireless sensor networks, write Lance Doherty, Jonathan Simon and Thomas Watteyne from Linear Technology While both low-power sensors and wireless networking are now ubiquitous, there are still relatively few examples on the market of low-power wireless sensor networks. This […]

TI claims zero drift op amp first

TI claims zero-drift op amp first

Description The OPA2188 operational amplifier uses TI proprietary auto-zeroing techniques to provide low offset voltage (25 µV, max), and near zero-drift over time and temperature. This miniature, high-precision, low quiescent current amplifier offers high input impedance and rail-to-rail output swing within 15 mV of the rails. The input common-mode range includes the negative rail. Either
