Sensitivity is defined as ratio between the output and input of the sensor. In the case of analog output gyroscopes, sensitivity is usually expressed as millivolts per DPS. As for the zero rate level, sensitivity is also reported both at ambient temperature and over the device’s specified temperature range. The formula shows how to get the angular rate from the voltage reading. Simply subtracting the Zero rate level from the output value, and dividing the result by the sensitivity expressed as millivolts per dps will provide the angular rate. The Sensitivity of ST’s gyroscopes is also characterized by the excellent temperature stability, with a variation of a fraction of a percent for each degree Celsius.
