DESCRIPTION
SWR200 is a Precision Sine Wave Reference
providing an ultra stable sine wave output of
7.071V at ±0.05% initial accuracy and
temperature coefficient as low as 3 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.
The SWR200 is available in a 14-pin bottom
braze package. They are hermetically sealed and
"M" versions 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
Analog Converter.
