Broadcom AEAT-9933 Programmable Angular Magnetic Encoders
Broadcom AEAT-9933 Programmable Angular Magnetic Encoders offer 10-bit to 14-bit programmable resolution for On- and Off-axis applications. These encoders are angular magnetic rotary sensors that provide accurate angular measurement over 360° rotation. The AEAT-9933 encoders use integrated Hall sensor elements with complex analog and digital signal processing within a single device. These encoders feature a 3.3V and 5V supply input voltage range, commutation angle output UVW 1 to 32 pole-pair, and programmable hysteresis. Typical applications include industrial automation, robotics, industrial sewing machines, textile equipment, brushless DC motors and stepper motors, and resolver and potentiometer replacement.
The AEAT-9933 encoders also feature absolute output over two-wire SSI, three-wire SSI, and four-wire SPI. These encoders include a flexible, incremental ABI resolution ranging from 1 CPR to 1024 CPR. The AEAT-9933 encoders are RoHS-compliant and available in the QFN-24 package.
