Test Structures

Two different test signal structures are implemented in the TLE5010. These are:

• Functional angle test. In this case, well-knows signals feed the ADCs.

• Temperature measurement. This is useful to read out the chip temperature for

compensation purposes.

11.1

Functional Angle Tests

It is possible to feed the ADCs with appropriate values to simulate a certain magnet-

position and other GMR effects.

The values are generated with resistors on the chip.

Following X / Y ADC values can be programmed:

• 4 points, circle amplitude = 70.7%

(0°, 90°, 180°, 270°)

• 8 points, circle amplitude = 100.0%

(0°, 45°, 90°, 135°,180°, 225°, 270°, 315°)

• 8 points, circle amplitude = 122.1%

(35.3°, 54.7°, 125.3°, 144.7°, 215.3°, 234.7°, 305.3°, 324.7°)

• 4 points, circle amplitude = 141.4%

(45°, 135°, 225°, 315°)

Note: The 100% values correspond to typically 21700 digits and a voltage of ~ 110 mV.
