AR25-AS02

AR25-AS02 is a programmable absolute encoder IC with ABI/UVW output. This series is a miniature absolute encoder ASIC designed to cater to the growing demand of space-constrained applications. AR25 encoder is a one-chip solution that has the flexibility to cater for variable overall diameters, ranging from 30mm to 60mm. AR25 also supports through-hole solutions up to 30mm in diameter. It also supports integration with Broadcom’s proprietary battery-less energy harvesting multi-turn (EHMT) solution. Alternatively, other multi-turn solutions like gear based and battery back-up are also supported via a dedicated MT interface port. Typical applications are robotic automation and engineering, factory automation and drone, medical and dentistry, devices and equipment, high-accuracy portable and handheld devices, miniature motor, servo motor, linear actuator.
