Data Sheet
8 Mode Input Pin
The mode input pin activates or deactivates an internal filter that is used to reduce the analog output noise.
Activating the filter (Mode pin = LOW) provides a reduced output noise of 0.03° rms. At the same time, the output
delay is increased to 384μs. This mode is recommended for high precision, low speed applications.
Deactivating the filter (Mode pin = HIGH) reduces the output delay to 96μs and provides an output noise of 0.06°
rms. This mode is recommended for higher speed applications.
The MODE pin should be set at power-up. A change of the mode during operation is not allowed.
Switching the Mode pin affects the following parameters:

If CSn changes to logic low, Data Out (DO) will change from high impedance (tri-state) to logic high and the read-out
will be initiated.
After a minimum time t CLK FE, data is latched into the output shift register with the first falling edge of CLK.
Each subsequent rising CLK edge shifts out one bit of data.
The serial word contains 18 bits, the first 12 bits are the angular information D[11:0], the subsequent 6 bits
contain system information, about the validity of data such as OCF, COF, LIN, Parity and Magnetic Field status
(increase/decrease).
A subsequent measurement is initiated by a “high” pulse at CSn with a minimum duration of t CSn.
