KMA200

Programmable angle sensor

[1]

Diagnosis GND and VDD lost only possible with a pull-up resistor of 5 k to 6 k.

[2]

Diagnosis VDD lost only possible with a pull-down resistor of 5 k to 6 k.

[3]

Load resistor required to enable the diagnosis features. Infinite resistor load permitted for normal operation without the diagnosis

features.

[4]

Analog outputs need to be low-pass filtered (corner frequency about 1.3 kHz).
