The Broadcom AR25 is a miniature absolute encoder ASIC designed for space-constrained applications. Utilizing advanced reflective optical-encoding theory, it offers high position accuracy with a correction algorithm superior to magnetic encoders. This one-chip solution supports variable overall diameters (30 mm to 60 mm) and through-hole solutions up to 30 mm. It provides user-programmable resolutions from 15-bit to 25-bit single-turn absolute outputs, as well as differential analog sine/cosine or digital incremental ABIUVW signals with configurable CPRs and pole-pairs. The AR25 features Auto-Calibration for simplified integration and supports integration with Broadcom's proprietary battery-less Energy Harvesting Multi-Turn (EHMT) solution, or other multi-turn solutions via a dedicated MT interface port. It operates on dual-mode 3.3V or 5V power supplies, suitable for handheld and portable devices, with an operating temperature range of 40C to 125C for industrial applications. The AR25 offers selectable communication protocols including Encoder Serial Link (ESL), RS485, SSI, BiSS-C, and SPI 4-wire.
