DESCRIPTION
SWR200 is a Precision Sine Wave Reference providing an ultra stable sine wave output of +7.071 V at ±0.5% initial accuracy and temperature coeffcient as low as 20 ppm/°C over the full military temperature range. The extreme accuracy is made possible by a chopper-based AGC circuit. The temperature characteristic of the chopper circuit compensates the typical nonlinearity of the internal DC zener reference, resulting in a nearly linear amplitude-temperature characteristic. Frequency of the SWR200 is programmable with two external capacitors.
