Datasheet KMA210 (NXP)

KMA210 Programmable angle sensor Rev. 2 — 7 December 2011 Product data sheet 1. Product profile 1.1 General description
The KMA210 is a magnetic angle sensor module. The MagnetoResistive (MR) sensor bridges, the mixed signal Integrated Circuit (IC) and the required capacitances are integrated into a single package. This angular measurement module KMA210 is pre-programmed, pre-calibrated and therefore, ready to use. The KMA210 allows user-specific adjustments of angular range, zero angle and clamping voltages. The settings are stored permanently in a non-volatile memory.
1.2 Features and benefits
