SWR200 SWSRW2R02000 Precision Sine Wave Reference FEATURES ♦ Very High Accuracy: +7.071 Vrms ±0.5% ♦ Extremely Low Drift: 20 ppm/°C (-55°C to +125°C) ♦ Excellent Stability: 10 ppm/1000 Hrs. Typical ♦ Low Distortion: 0.1% Thd @ f = 3300 Hz ♦ Hermetic 14-pin Ceramic DIP ♦ Military Processing Option APPLICATIONS ♦ Transducer Excitation ♦ High Resolution Servo Systems ♦ High Precision Test and Measurement Instru- ments ♦ AC Voltage Standard ♦ LVDT Or RVDT Reference ♦ Multiplying D/A Reference 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 coefficient 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-temper...
