Apex Microtechnology SWR200 Precision Sine Wave Reference
Apex Microtechnology SWR200 Precision Sine Wave Reference provides a stable +7.071V at ±0.5% sine wave output and a 20ppm/°C temperature coefficient over the full military temperature range. Extreme accuracy is achieved by a chopper-based AGC circuit. The temperature characteristic of the chopper circuit compensates for the typical nonlinearity of the internal DC Zener reference, resulting in a near-linear amplitude-temperature characteristic. The frequency of the Apex Microtechnology SWR200 is programmable with two external capacitors.
