SWR200

Precision Sine Wave Reference

FEaTuRES

DESCRIPTION

SWR200 is a Precision Sine Wave Reference provid-

ing an ultra stable sine wave output of +7.071 V at

±0.05% initial accuracy and temperature coefﬁcient

as low as 30 ppm/°C over the full military temperature

range. The extreme accuracy is made possible by a

chopper-based AGC circuit. The temperature charac-

teristic of the chopper circuit compensates the typical

nonlinearity of the internal DC zener reference, result-

ing in a nearly linear amplitude-temperature character-

istic. Frequency of the SWR200 is programmable with

two external capacitors.

♦ Very High Accuracy: +7.071 Vrms ±0.05%

♦ Extremely Low Drift: 30 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

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.

♦ AC Voltage Standard

♦ L_VDTOr R_VDTReference

♦ Multiplying D/A Reference

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 L_VDTor R_VDTposition sensors. A programmable AC

reference can be constructed using the SWR200 as

a reference for a high accuracy multiplying Digital to

Analog Converter.
