Product data sheet Rev. 1 — 24 May 2012 5 of 36 NXP Semiconductors KMA220 Dual channel programmable angle sensor Since the Anisotropic MR (AMR) effect is periodic over 180 , the sensor output is also 180 -periodic. The angle is calculated relative to a freely programmable zero angle. The dashed line indicates the mechanical zero degree position. 6. Analog output The KMA220 provides two analog output signals on pin OUT1/DATA1 and on pin OUT2/DATA2. The measured angle is converted linearly into a value, which is ratiometric to the supply voltage VDD. Either a positive or a negative slope can be programmed independently for each pin by the customer for this purpose. Table 3 describes the analog output behavior for a positive slope. If for example, a magnetic field angle, above the programmed maximum angle max, but below the clamp switch angle sw(CL) is applied to the sensor, then analog output is set to the upper clamping voltage. If the magnetic field angle is larger than the clamp switch angle, the analog output switches from upper to lower clamping voltage. If there is a negative slope, the clamping voltages are changed. The analog output voltage range encodes both angular and diagnostic information. A valid angle value is between the upper and lower clamping voltage. If the analog output is in the diagnostic range, that is below 4 %VDD or above 96 %VDD, an error condition has been detected. The analog output repeats every 180 . Fig 2.
