KMA199
Programmable angle sensor
8. Limiting values
[1] Time until sensor environment is initialized.
[2] The maximum value of the output voltage is 5.7 V.
9. Recommended operating conditions
[1] Normal operating mode.
[2] Between ground and analog output, as close as possible to the package for improved electromagnetic
immunity.
[3] Between ground and supply voltage, as close as possible to the package and with a low equivalent series
resistance.
[4] Power-loss detection is only possible with a load resistance within the specified range connected to the
supply or ground line.
