SWR200数据手册APEX中文资料规格书

描述 Description

SWR200 is a precision sine wave reference providing an ultra stable sine wave output of +7.071V at ±0.5% initial accuracy and a temperature coefficient as low as 20 ppm/°C over the full military temperature range. This 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 near linear amplitude-temperature characteristic. Frequency of the SWR200 is programmable with two external capacitors.

The SWR200 series is available in a 14-pin bottom braze hermetically sealed package, and a “M” version 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.
