DESCRIPTION
SWR200 is a Precision Sine Wave Reference providing an ultra stable sine wave output of +7.071V at
±0.5% initial accuracy and temperature coefficient as low as 20ppm/°C over the full military temperature
range. The extreme accuracy is made possible by a chopper-based AGC circuit. The temperature characteris-
tic 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.
The SWR200 is available in a 14-pin bottom braze package. They are hermetically sealed and “M” ver-
sions are screened for high reliability and quality.
SWR200 is well suited for any application requiring a stable sine wave source. The SWR200 can be used as
a reference source in precision sensing systems based on LVDT or RVDT position sensors. A programmable AC
reference can be constructed using the SWR200 as a reference for a high accuracy multiplying Digital to Ana-
log Converter.
