Ar18/ar35 Series Single-turn Absolute Encoders

Broadcom’s AR18 and AR35 series miniature programmable single-turn absolute encoders with resolution ranging from 17-bits to 21-bits

Ar18 ar35 Series Single-turn Absolute Encoders

Broadcom’s AR18 and AR35 series are the miniature absolute encoder ASICs designed to cater to the growing demand for space-constrained applications. The AR18 encoder is designed for an overall diameter of 18 mm and offers user-programmable resolution ranging from 17-bit, 19-bit, and 21-bit single-turn absolute output. The AR35 encoder is designed for an overall diameter of 35 mm and offers 17-bit and 21-bit single-turn absolute output. Both the AR18 and AR35 series provide the incremental ABI and UVW in differential mode. Both come with a recommended temperature range of -40°C to +115°C suitable for most industrial applications. Dual-mode operating voltages of 3.3 V and 5 V enable handheld and portable device applications.
