Overview

ADI’s ADM3061 and ADM3062 are half-duplex RS-485 transceivers, fully compliant to the Profibus® standard with increased 2.1 V bus differential voltage at VCC ≥ 4.5 V. The ADM3062E features a VIO logic supply pin allowing a flexible digital interface capable of operating as low as 1.62 V.The ADM3061 and ADM3062 have a ¼ unit load input impedance, which allows up to 128 transceivers on a bus. The ADM3061 and ADM3062 models feature a low 500 kbps data rate suitable for operation over long cable runs. The RS-485 transceivers are available in many space-saving LFCSP, MSOP, and SOIC packages. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. If during fault conditions a significant temperature increase is detected in the internal driver circuitry, this feature forces the driver output into a high impedance state. The ADM3061 and ADM3062 guarantee a logic high receiver output when the receiver inputs are shorted, open, or connected to a terminated transmission line with all drivers disabled. These transceivers are ideal for process control, building automation, and motor control applications.Features: TIA/EIA RS-485 compliant over full supply range, 3.0 V to 5.5 V operating voltage range on VCC, 1.62 V to 5.5 V VIO logic supply, ESD protection on the bus pins  IEC 61000-4-2 ≥ ±12 kV contact discharge, IEC 61000-4-2 ≥ ±12 kV air discharge, HBM ≥ ±30 kV, Low speed 500 kbps data rate for long cables, Full hot-swap support (glitch free power-up/power-down), Full receiver short-circuit, open circuit, and bus idle fail-safe, Extended temperature range up to +125°C, Profibus compliant at VCC ≥ 4.5 V, Half-duplex, Allows connection of up to 128 nodes onto the bus, Process control, Building automation, Profibus networks, Motor control server drives and encoders, Industrial fieldbus
