ADXRS652 ADXRS652 AND SUPPLY RATIOMETRICITY SELF-TEST FUNCTION The ADXRS652 RATEOUT and TEMP signals are ratiometric The ADXRS652 includes a self-test feature that actuates each of to the V voltage; that is, the null voltage, rate sensitivity, and the sensing structures and associated electronics in the same RATIO temperature outputs are proportional to V . So the ADXRS652 manner, as if subjected to angular rate. It is activated by standard RATIO is most easily used with a supply-ratiometric analog-to-digital logic high levels applied to Input ST1 (5F, 5G), Input ST2 converter, which results in self-cancellation of errors due to minor (4F, 4G), or both. ST1 causes the voltage at RATEOUT to change supply variations. There is some small error due to nonratiometric about −0.5 V, and ST2 causes an opposite change of +0.5 V. The behavior. Typical ratiometricity error for null, sensitivity, self-test, self-test response follows the viscosity temperature dependence and temperature output is outlined in Table 4. of the package atmosphere, approximately 0.25%/°C. Note that V must never be greater than AV . Activating both ST1 and ST2 simultaneously is not damaging. RATIO CC ST1 and ST2 are fairly closely matched (±5%), but actuating Table 4.
