Q
We are very interested in your ADXRS800 Angular Rate Sensor for civil camera platform stabilization purposes. Could you please provide further information on -) Sensor resoultion -) Throughput time -) Group delay -) Max. sampling time -) Max. SPI data rate -) Noise characteristics
A
Before I get started, I wanted to point out that the ADXRS800 is intended for Automotive applications. If your application is camera platform stabilization, I would recommend you to check with ADXRS450 and ADXRS453. These products are similar to the ADXRS800, but they are specifically intended for I&I markets. The ADXRS450/3 and the ADXRS800 are pretty similar. Could you please provide further information on -) Sensor resolution – [MH] The resolution of this gyro is 80LSB/°/s. -) Throughput time [MH] see answers for “group delay” and “sampling time”. Any signal delays beyond those two are negligibly small. -) Group delay [MH] 4ms. -) Max. sampling time [MH] 500Hz (2ms) -) Max. SPI data rate – [MH] Fresh data samples are generated at a 500Hz rate. The Max clock speed for the SPI interface is 8MHz. -) Noise characteristics [MH] max noise over temp is 0.04 °/s/rtHz (roughly 0.4°/s rms)
