- .. IC 1 ’s feedback input rests at 0.8 V, and IC 2 and R 2 form a voltage divider. The ADSP-BF531 imposes several design requirements: Its core power-supply voltage must maintain its accuracy to within 25 mV and offer an ...25-01-2024
- .. previous Design Idea “Gated 555 astable hits the ground running” ( Ref. 1 ) offered a fix for the problem of the ...23-01-2024
- .. rather than linear. The response to varying input levels is shown in Figure 4. I chose to use a full-scale reading of +10 dBu, the normal operating level being around 10 dBu with clipping starting at ~+16 dBu. For lower maximum readings, ...
.. log of the input signal. Positive input half-cycles cause it to clamp low at V F , which we ignore, as this is a half-wave design; for negative ones, it swings high by 2V F . Driving that 2V F through another diode into the capacitor ...22-01-2024 - .. comparable to a 74HC04. Figure 5. A buffer may be necessary to provide a full voltage excursion RESET signal. Oscillator design equations are unchanged from the usual 555 datasheet math, except that the timing capacitance used should be ...18-01-2024
- .. is roughly 100 kHz under control of the U1c Schmidt trigger style oscillator, so that a charge transfer occurs every 10 µs. Note the positive feedback around U1c via R3 and inverse feedback via R1, R2, and C1. The resulting ...
.. at and below zero volts, generating symmetrical output signals, and processing bipolar analog inputs, are all examples of design situations where a few milliamps of negative voltage rail can be a necessity. Figure 1 shows a simple ...10-01-2024 - .. by R6 and D6, which track R1 and D2 in the oscillator itself. A4 buffers the output, which is now almost constant below 10 kHz and only 10% up at 25 kHz. (LDR1 was a Silonex NSL-19M51, the LED being a generic T-1 clear white 8 cd device, ...09-01-2024
- .. on, what of the others? A simple twin-tee notch filter with feedback, built for close to 1 kHz with a Q of 2 and a gain of 10, allowed the scope’s rather basic FFT to reveal harmonics previously buried in the sampling noise. This clearly ...
.. exponential waves are much use for generating sines, especially when their amplitudes depend on the supply. (My original design spec was for a PP3/6LR61 battery, giving about 9 V or 4.5 V when new, and a lot less when not.) A different ...08-01-2024 - .. associated with the circuit in Figure 1. T 1 is a signal transformer that you can modify by wrapping two turns of 14-gauge wire around the bobbin to act as the primary winding. Materials on the topic Datasheet Texas Instruments LM311 ...
.. Note that the signal ground with respect to earth ground is floating; you must not tie these grounds together. The design in Figure 1 has successfully controlled fans and high-amperage universal motors (100 mA to 11 A). One example ...01-01-2024 - .. back I published a simple design idea for a thermal airspeed sensor based on a self-heated Darlington transistor pair ( Ref. 1 ). See Figure ...29-12-2023
- .. 3 V, the linear driver takes over. Note that if the other half of the LM393 is not used for another LED power supply, good design practice dictates that all unused input and output pins on the LM393 be tied to ground. Figure 2 shows the ...28-12-2023
