Linear Technology Corporation announces the LTC3897, a multiphase synchronous boost DC/DC controller with input surge stopper and ideal diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus the single-phase equivalent. Synchronous rectification increases efficiency, reduces power loss and […]

Choosing a temperature-measurement sensing method
Temperature is a parameter that often needs measuring. It may be within an enclosure, on a PCB, remotely or even “wirelessly”. Wireless, in this case, does not necessarily mean a remote sensor communicating using radio frequencies, it can mean a pyroelectric sensor. Pyroelectric sensors are very long wavelength detectors which measure radiation in the 6-15μm […]
Mesh networks get new networking software and low-power mode
Linear Technology’s SmartMesh IP™ wireless sensor network (WSN) product line has expanded to address the growing needs of industrial Internet of Things (IoT) applications. New capabilities include the SmartMesh® VManager™ networking software, which seamlessly increases the mesh network capacity to thousands of nodes. The new Blink mode, an ultralow power roaming node capability, reduces average […]

Today’s wireless power transfer
Wireless power transfer has been around for a long time. The “crystal set” or “crystal radio” over 100 years ago used the power carried in the radio signal to produce sound without any amplification or receiving circuit power source. Early spark gap transmitters also used tuned wireless power transmission. Now the circuitry is more sophisticated […]
SAR 16-bit ADC digitizes up to up to 750 kHz
Linear Technology Corporation introduces the LTC2320-16, a 16-bit 1.5Msps per channel, no latency successive approximation register (SAR) ADC with eight simultaneously sampling channels supporting a rail-to-rail input common mode range. The LTC2320-16 features a flexible analog front end that accepts fully differential, unipolar or bipolar analog input signals, as well as arbitrary input signals, and […]
