either when the supply is interrupted or
when the magnetic field is in the “red” range,
(see Table 3) the output is switched to 0V
and thus indicates the error condition.

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:

with pull down resistor at DO (receiving
side), all bits read by the SSI will be “0”-
s, indicating a non-valid output
(V OUT pull up resistor at receiving side)
*) Vref = internal: ? * VDD5V (pin #16) or external: V DACref (pin#9), depending on Ref_extEN bit in OTP (0=int., 1=ext.)
**) VDD = positive supply voltage at receiving side (3.0 – 5.5V)
