- Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors' resistance-versus-temperature characteristics are highly ...15-06-2021
- For safety reasons, a motor that drives a safety-critical electromechanical assembly often includes an electromagnetic brake on its drive shaft. The brake typically comprises a solenoid coil that actuates a mechanical clutch, and, when you power ...09-06-2021
- 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 ...31-05-2021
- Most microprocessors have some type of hardware watchdog that can be used to reset the microprocessor and the surrounding hardware to a known state if firmware inadvertently stops executing code. But it may be advantageous to record the ...24-05-2021
- 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 ...19-05-2021
- 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 ...18-05-2021
- Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the motor often cannot go from 0 rpm to the desired ...10-05-2021
- Speed controllers have long exploited the reverse-EMF characteristics of dc motors to control their speed. These linear driver circuits use power op amps to create a negative resistance drive to the motor that counteracts the voltage drop in the ...26-04-2021
- 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) ...14-04-2021
- The circuit in Figure 1 uses the LM358 dual op amp running as a comparator, plus a few other inexpensive components, to make a TTL (transistor- transistor-logic)/CMOS-logic probe. The circuit gets its power from the circuit under test, which lets ...08-04-2021
