The ADXRS645 has a default range of ±2000 °/sec and a scaling of 1 mV/°/sec which equates to 0.5V to 4.5V centred around 2.5V. If the ±5000 °/sec option is implemented is full scale still 0.5V and 4.5V. Or should I use 0V and 5V?…

What is the relationship for increasing the range on the ADXRS645?

RANGE EXTENSION

The ADXRS645 scale factor can be reduced to extend the measurement range to as much as ±5000°/sec by adding a single 120 kΩ resistor between the RATEOUT and SUMJ pins…

## Is it possible to get the altium footprints for the ADXRS645?

Or failing that the altium or gerber files for the EVAL-ADXRS645?

I ask as I've used the bxl file and although not obviously wrong i don't think the tolerances stack up vs the datasheet. Plus…

In my application is it probable the ADXRS645 will suffer shock impacts in use, rather than changes in rotation speed.
Sorry I can't an exact figure on shock at present. Think in terms of tens of G.

What level of shock is likely to produce erroneous…

• ### 我们购买了两片ADXRS645，想了解如下问题： 1、Vratio引脚（F2引脚）在数据手册中推荐采用的是+5V电压，我能够用+2.5V电压吗？ 2、若Vratio引脚采用+2.5V，是否RATEOUT引脚初始零点输出就变成了1.25V。然后理论上最高正向转速输出+2.5V，最高负向转速就变成了0V输出？ 我这样理解参数与Vratio成线性比率是正确的么？

The new ADXRS645 gyro looks like it could suit our requirements for but we have restrictions on where we can mount the device, a central bore with fluid flow will not allow us to locate it so that the rate axis rotation will be dead centre. Can the gyro…
