AS5046 Programmable 360° Magnetic Angle Encoder – Preliminary Data Sheet
It is possible to enable the analog output permanently (it will not be switched off even if the magnetic field is out of range).
To enable this feature an OTP bit in the factory setting must be set. The corresponding bit is FS6. See application note
AS5040-20 (Extended features of OTP programming) for further details. The application note is available for download at the
austriamicrosystems website.
The analog and digital outputs will have the following conditions:
