Low Distortion Sine Wave Generator Circuit

The xr 2206 is an older ic that is still available and a great way to generate sine square and triangle waves over a wide frequency range.

Low distortion sine wave generator circuit.

In this circuit we use a zener diode in performs this function to limit a voltage. This circuit generates a good 1khz sinewave adopting the inverted wien bridge configuration c1 r3 c2 r4. If you need a sine wave generator that can be set to any frequency in the 0 01 hz to 1 mhz or more take a look at the xr 2206. Low noise low distortion sine wave generator for testing adc demo boards demonstration circuit 1858a is a low noise low distortion sine wave generator designed to be used in conjunction withlineartechnology 16 bit and 18 bit adc demoboards.

1 is a reasonably easy technique depending on the well known wien bridge. Functionally this board uses a wien bridge oscillator that. It features a variable output low distortion and low output impedance in order to obtain good overload capability. The output of the ltc1968 equals the rms level of the sine wave divided by 3.

Figure 7 shows the xr 2206 connected as a sine wave generator. The vlf sine generator circuit demonstrated in fig. Sine wave oscillator low frequency. Schematic of the sine wave oscillator consisting of a low distortion lt1632 based wien bridge oscillator core and an ltc1968 controlled amplitude stabilization loop.

And the active devices in the circuit q1 q2 will need to has a gain ratio nearly three times so will complete to produce.
