• Manufacturer Part Number: tle5011
• Description: Gmr Based Angular Sensor
• Manufacturer: Infineon Technologies Corporation

Two different test signal structures are implemented in the TLE5011. These are:
• Functional Angle Test. In this case, well-known signals feed the ADCs.
• Temperature Measurement. This is useful to read out the chip temperature for
11.1
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%
• 8 points, circle amplitude = 100.0%
• 8 points, circle amplitude = 122.1%
• 4 points, circle amplitude = 141.4%
Note: The 100% values typically correspond to 21700 digits and a voltage of ~ 110 mV.
