.. all that’s needed to linearize the 0 C to 100 C response to better than 0.1 C. So, cheaper, simpler, superior power efficiency, and more accurate. Cool! Thanks for the suggestions, guys! References Woodward, Stephen. The power ...
.. high-side current-sense amplifier, IC 1 , offers a simple method of combining low-speed clocks or other signals with dc power in cables between subsystems (Figure 1). Designed for monitoring charge and discharge current in secondary ...
Frequent contributor Nick Cornford recently published a delightfully clever design idea ( Reference 1 ) using a platinum RTD calibrated to output a 1 mV/ C signal that’s perfect for direct readout via a standard DMM I thought Nick’s ...
.. damping of the meter movement. For example, suppose that your application requires measurement of a 0 to 10 V power supply (Figure 1). You have available a typical electromechanical meter that presents a full-scale voltage ...
.. is generated. In another position, an “OFF” delay is generated. The load can be connected between Q1 and the power supply (across LED + R6), which can be switched “ON” or “OFF” after the time delay. U1 ...
.. to their coils. Because these relays require no continuous coil currents to keep their states, you can save considerable power in the driver circuit. In one type of latching relays, you can alternately energize dual coils to change the ...
.. it’s operated in linear or pulse mode, high efficiency is virtually guaranteed. This happens simply because when the power pass device and heater are combined, power dissipated isn’t wasted. Instead, by definition, it’s ...
.. current of the plain old 555 timer. From the block diagram in Figure 1 taken from the datasheet of the ST’s TS555 low power single CMOS timer) we can see that the Discharge pin (pin 7) repeats the Output pin (pin 3). In reality, they ...
.. one-wire bus ( Reference 1 ). The circuit uses approximately 150 µA of current, allowing the circuit to steal its power from the bus via the Schottky diode, D 1 . Because the circuit is sensing water that is part of the electrical ...
.. to convert the current signal into a voltage signal. Accidentally connecting the precision shunts to the current-loop power supply can cause damage, after which you must replace the shunt and recalibrate the system. To avoid that ...
