Vishay Intertechnology introduced a new high precision thin film wraparound chip resistor for industrial, medical, military, and aerospace applications. The Vishay Sfernice P2TC offers a tight TCR of ±2 ppm/°C over wider resistance and temperature ranges...
Simple Technique Drives Multiple LEDs From One Processor Pin
Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple RC networks to distinguish between them. The design described here is much simpler...
Würth Elektronik has released a new series of low-voltage clock oscillators
As technology evolves, devices need to run at lower and lower voltages and this means that systems may need to have multiple supply rails. Because of this IQD, a subsidiary of the Würth Elektronik eiSos Group, have produced a range of frequency products...
Frequency doubler operates on triangle wave
Frequency multipliers typically work with square waves. However, the circuit in Figure 1 performs frequency multiplication on triangle waveforms and maintains the input's amplitude and uniformity...
