The simple ADC in Figure 1 is perfect for getting analog signals into a purely digital microcontroller. Using just five surface-mount parts, you can assemble it for less than 50 cents (1000), which is approximately half the cost of a ...

Deadband circuits find applications in servo-control systems. A precision current source and a half-wave inverting rectifier form a positive deadband circuit (Figure 1). The REF01 , IC 1 , is a precision 10 V voltage reference. It forms a precision ...

A typical window comparator uses two comparators and a single op amp to determine whether a voltage is inside or outside a boundary region. Figure 1 shows a typical implementation. IC 1 is an inverting op amp with a gain of 1. V REF and V REF ...

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. Figure 1. This circuit performs frequency ...

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 ...

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 (infrared) ...

The gate-turn-on threshold voltage for GaAs MESFETs (gallium-arsenide metal-semiconductor field-effect transistors) varies considerably from part to part, even within a given lot. That behavior makes biasing difficult, especially if you want to ...

Instrumentation amplifiers serve in a variety of applications that need to extract a weak differential signal from large common-mode noise or interference. However, designers often overlook the potential problem of RF rectification inside the ...
