GENERAL DESCRIPTION
A sub range can be programmed to achieve the best resolution for the application. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.087º = 4096 positions per revolution. The start and end point of the sub segment will be programmed with a resolution of 14-bit (0.022º= 16384 steps per revolution). According to this resolution the adjustment of the application specific mechanical positions are possible. The angular output data is available over a 12-bit PWM signal or 12-bit ratiometric analog output. An internal voltage regulator with over voltage protection and reverse polarity protection allows the AS5263 to operate in automotive application up to a voltage to 27V. Programmability over the output pin reduces the number of pins on the application connector.
