Wein … WebOccasionally R53/RA53 thermistors appear on on-line auction sites, but these are a rather unreliable source at the best of times. Any waveform can be converted into a sinewave if you apply enough filtering, but unless the filter is part of the oscillator it is difficult to impossible to make the filter and oscillator track perfectly.

WebSep 15, 2011 · So, using the RA53 and a NE5532 op-amp, it only took about an hour to make an oscillator that ran off a couple of 9v batteries, and measured about 0.007% THD at 10kHz on my analyser. (The remaining THD is probably a combination of ignoring Williams’ Law, thermal modulation in the thermistor, and the dirty mains in our lab.) 7.

Although all resistors’ resistance will fluctuate slightly with temperature, a thermistor is particularly sensitive to temperature changes. Thermistors act as a passive component in a circuit. iberiabank interest rates
