The original application for the circuit was to check the number of revolutions of an engine with only one LED as an indicator. The measurement of the number of revolutions usually involves sensors with a frequency output proportional to the number of revolutions...

Vishay Intertechnology released a new bidirectional symmetrical 2-line ESD protection diode in the compact DFN1110-3A package with wettable flanks...

Texas Instruments introduced the wideband, low-noise operational amplifier OPA855-Q1 with bipolar inputs for wideband transimpedance and voltage amplifier applications...

The two-chip circuit provides fan control and overtemperature warning and shutdown signals to protect systems from excessive heat. The circuit monitors the temperature of the pc board and the die temperature of a CPU, an FPGA, or another IC with an on-chip temperature-sensing transistor...

Power Integrations announced a new member of its acclaimed LinkSwitch™-TN2 AC-DC converter family. The new LNK3207 ICs facilitate higher-power offline buck converter designs for appliances and industrial applications by increasing the available output current from 360 mA to 575 mA, while also reducing BOM count...

Accurate op amps have high open-loop gain, low offset voltage and current, low voltage and current noise, and low distortion. However, they often lack the ability to provide high output currents while maintaining all the other high-accuracy specifications...

Lumileds and BIOS unite their expertise to achieve LED efficacy, color consistency and melanopic ratios that will drive development and adoption of circadian lighting...

Resistive dividers attenuate high voltages down to a level that low voltage circuits can accommodate without getting overdriven or damaged. In power path control circuits, resistive dividers help set up power supply undervoltage and overvoltage lockout thresholds...

Infineon Technologies announced the launch of the XENSIV IM67D130A. This new device combines the Company’s expertise in the automotive industry with its technical leadership in high-end MEMS microphones...

Light sensors find use in a host of important applications, spanning from consumer electronics, such as ambient-light measurements and exposure control for cameras, to scientific instruments, such as optical-absorption spectroscopy, IR detection for thermography, and two-color pyrometry...
