Analog Devices Inc. ADXRS645 陀螺仪
亚德诺半导体 ADXRS645 高温、抗振动陀螺仪是一款高性能角速率传感器，具有出色的抗振动能力，可用于高达 175ºC 的高温环境。采用 ADI 公司获得专利的 高容量 BiMOS 表面微加工工艺进行开发， ADXRS645 高级的差分、四通道传感器设计 提供了出色的加速和振动抑制性。输出信号 RATEOUT 是一个电压值，与关于垂直于封装上表面的轴转动的角速度正比例。最小测量范围为 ±2000°/秒, 加入单个外部电阻之后可扩展至 ±5000°/秒。输出与所提供的基准电源成比率。还需要其它若干外部电容来运行。ADXRS645 提供温度输出，实现补偿方法。两路数字自测输入通过机电方式激发传感器，以测试传感器和信号调理电路是否正常工作。ADXRS645 采用 8mm × 9mm × 3mm、15 引脚钎焊引脚三列直插式封装，特别适合于严苛的机械环境、极高温的工业应用、以及地质勘探中的 井下测量。
The measurement range is a minimum of ±2000°/sec, and may be extended to ±5000°/sec with the addition of a single external resistor. The output is ratiometric with respect to a provided reference supply. Other external capacitors are required for operation. ADXRS645 includes a temperature output for compensation techniques. Two digital self-test inputs electromechanically excite the sensor to test proper operation of both the sensor and the signal conditioning circuits. Available in a 8mm × 9mm × 3mm, 15-lead brazed lead tri in-line package, ADXRS645 is ideal for severe mechanical environments, extreme high temperature industrial applications, and down-hole measurements for geological exploration.
