    Figure 1’s silly-simple voltage-to-time ADC is an exercise in dynamic range. Assuming that it is used with a 10-MHz counter/timer, its resolution is roughly 10 µV per count for inputs around 0 V and 100 mV per count at 1 kV, and it ...

    Short-circuit protection is an obvious requirement for a power supply, especially when its load connects to a cable that's subject to damage. Many modern power-converter ICs include some means of protection, such as thermal shutdown, against ...

    Figure 1 shows how to position a mechanical device into four discrete positions but with only two free outputs and one free input from the control system. The position depends on a set of cams and four corresponding limit switches. The 24V-dc motor ...

    Figure 1 shows an example of on/off circuitry commonly used in battery-operated devices. The p-channel MOSFET, Q 1 , serves as a power switch. When you push the On button, S 1 , Q 1 ’s gate goes low. Q 1 turns on and supplies battery voltage ...

    Instead of the conventional approach of backing up a DAC with an amplifier to boost output, this design idea charts a less traveled by path to power. It integrates an LM317 positive regulator with a simple 8-bit PWM DAC topology to obtain a robust ...

    Figure 1 is a cheap and cheerful voltage inverter I offered awhile back in “A simple, accurate, and efficient charge pump voltage inverter for $1” ( Ref. 1 ). Figure 1. The generic and versatile xx4053 provides the basis for a cheap, ...

  7. Using the MAX4373 high-side current-sense amplifier, a circuit can be designed with a voltage range to 28 V. All that is needed is a general-purpose NPN transistor. The latching-comparator output (COUT1) on the MAX4373, a high-side current-sense ...

    ADC circuits that resolve signal into 20 or more bits need a low-noise signal source for measuring parameters such as harmonic distortion or effective number of bits. A notch filter removes the fundamental frequency from the oscillators signal for ...
