11.2 Output mode configuration (DSPMODE, OUTMODE)
DSPMODE activates the PWM or the analog mode for the output signal. OUTMODE configures the output
driver.

Output Driver
Fast analog mode, CL = 1nF..10nF(1) (2)(3)
Normal analog mode, CL = 5nF..50nF (1) (2)(4)
PWM mode – Open drain
PWM mode – Push pull
Table 13: Output configuration
(1) See section 16, CL = C4.
(2) Factory setting: DSPMODE = 0, OUTMODE = 1.
(3) For applications directly integrated on a PCB, smaller capacitors are allowed at the output pins.
(4) For a standalone application where a cable is connected at the output of the sensor.
11.3 Output impedance mode (DIAGINFAULT)
DIAGINFAULT sets the output impedance mode.

11.4 Reference edge (REFEDGE) – only in PWM mode
REFEDGE defines the diagnostic level and sets the reference edge.
