Broadcom AEAT-9922 Magnetic Encoder ICs

Broadcom AEAT-9922 Magnetic Encoder ICs are angular magnetic rotary sensors that provide accurate angular measurement over a full 360° of rotation. These sophisticated systems use integrated Hall sensor elements with complex analog and digital signal processing within a single device. The AEAT-9922 ICs feature 10-bits to 18-bits of absolute resolution and 1CPR to 10000CPR of incremental ABI resolution range. These encoder ICs operate within a -40°C to +125°C temperature range and are available in a compact QFN-24 leads package. The AEAT-9922 ICs are a versatile solution that supports a broad range of applications with robust architecture to measure and deliver absolute and incremental signals.
