Analog switch integrated chips (ICs), then turned on, will conduct both analog and digital signals from the input pin to the output pin. Digital switches can only accept digital signals and duplicate the logic level on the input pin at the output pin. When the digital switch is turned off, it returns to a default […]

The importance of Fourier Transforms
I have mentioned Fourier transforms in other posts but it is probably worthwhile explaining more about Fourier transforms in order to show why I think they are so important to analog signal processing. You may come across several theorems containing the name “Fourier” such as the Fourier Series, Fourier Transform, Fourier Integral and Fourier Analysis. […]

Straight waveguide sections cover WR-10 to WR-137 sizes
Pasternack, a leading provider of RF, microwave and millimeter wave products, has released a new series of straight waveguide sections in sizes ranging from WR-10 to WR-137. Typical applications include instrumentation, test benches, high-efficiency RF/Microwave transmission, SATCOM, MILCOM, radar and telecom networks. Pasternack’s new line of straight waveguide sections consists of 62 models that operate in the […]
Selecting an op amp
You could start with a similar op amp from a similar, known-good circuit or reference design and extrapolate from there. However, not everything labeled a reference design has actually been built and tested. But there’s another way to get organized and feel in control of the selection process. A methodical approach is outlined below that […]

Robust 3D transponder coils with high sensitivity for automotive
TDK Corporation presents a new series of 3D transponder coils with a high sensitivity level for passive entry passive start (PEPS) and other access systems. Measuring just 11.5 mm x 12.5 mm x 3.6 mm, the B82453C*A* series features six types of 3D transponder coils that offer sensitivity levels from 45 mV/µT to 83 mV/µT […]
What is a multiplying DAC?
Multiplying digital-to-analog converters (MDACs) produce a (current) output signal that’s a product of the given reference voltage and the code (i.e., a string of 0s and 1s) flowing through it. All data converters require a voltage reference (VREF) and a typical, standard DAC needs a very stable fixed reference voltage in order to operate properly. […]
Low-power piezo vibrator brings annunciation to wearable devices
Murata Americas today introduced the PJFV series. This miniaturized, low power consuming product leverages piezoelectric ceramics to provide vibration notifications and announcements to wearable devices. It measures just 10.5mm ´ 3.8mm ´ 2mm, has a rated working voltage of 3V, and current consumption of 2mA rms. Light and sound sensing products have historically been used for notification and announcement functions. With the roll-out of the PJFV series, now vibration solutions can […]
16-channel, 12/16-bit DACs target telecom optical-module control
Analog Devices, Inc. announced today a pair of highly integrated 16-channel digital-to-analog (D/A) converters that significantly reduce the system footprint for wired telecommunications systems, yet without any performance compromise. The 12-bit AD5767 and 16-bit AD5766 are fully integrated devices with all the required bias ranges for coherent optical systems of medium- to long-haul, fiber-based telecommunication […]
