This article explains the basis for achieving an optimized board layout, a critical aspect in the design of switch-mode power supplies. A good layout ensures stable functioning of the switching regulator and minimizes radiated interference as well ...
A spectrally pure sine wave oscillator is required for data converter; filter and audio testing. Figure 1 provides a stable frequency output with extremely low distortion. This quartz stabilized 4 kHz oscillator has less than 9 ppm (0.0009%) ...
You can effectively double the sample rate of a DAC by interleaving two DACs into a single unit. Updating each DAC on an alternating basis and switching to the appropriate output double the effective throughput of the overall system. It is ...
Digital potentiometers (digiPOTs) are versatile and can be used in a wide variety of applications, for example, for filtering or generating ac signals. However, sometimes the frequency must be able to be varied and adapted to the desired ...
ADCs with differential inputs are becoming increasingly popular. This popularity isn't surprising, because differential inputs in the ADC offer several advantages: good common-mode noise rejection, a doubling of the available dynamic range ...
Machine vision systems use very short flashes of intense light to produce high speed images used in a wide variety of data processing applications. For instance, fast moving conveyor belts are run through machine vision systems for quick label and ...
Ground Plane There is much more to discuss than can be covered here, but we’ll highlight some of the key features and encourage the reader to pursue the subject in greater detail. A list of references appears at the end of this article. A ...
You can use an ADT7461 single-channel temperature monitor; an ADG708 low-voltage, low-leakage CMOS 8-to-1 multiplexer; and three standard 2N3906 p-n-p transistors to measure the temperature of three separate remote thermal zones (Figure 1). ...
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 ...
You sometimes need to measure a small signal in the presence of a large common-mode signal. Traditional instrumentation amplifiers that use two or three op amps in their internal structure find common use in these applications. The circuit in ...
