What are the key features of ADM488ARZ?
- Single-driver, single-receiver half-duplex RS-485/RS-422 transceiver supports data rates up to 10 Mbps
- Differential Schmitt trigger inputs provide 0.2 V hysteresis for high noise immunity on industrial bus lines
- SOIC-8 package (MS-012AA) simplifies drop-in replacement of legacy RS-485 transceivers with standard 1.27 mm pitch
What is ADM488ARZ used for?
ADM488ARZ serves industrial automation and building control applications that use RS-485 multi-drop networks spanning up to 1200 m with up to 32 unit loads on a single bus. It is well suited for HVAC controllers, motor drives, and PLCs that require robust half-duplex communication at data rates up to 10 Mbps. The device also fits instrumentation and data acquisition systems where differential signaling must reject common-mode noise of ±7 V.

Frequently Asked Questions
What maximum data rate does ADM488ARZ support on an RS-485 bus?
ADM488ARZ is rated for data rates up to 10 Mbps on RS-485 and RS-422 buses. At this rate, cable length should be kept below 15 m to maintain signal integrity; at lower rates such as 100 kbps, cable runs of up to 1200 m are achievable with a 120 Ω termination resistor at each end of the bus.
How many RS-485 nodes can share a bus when using ADM488ARZ?
Each ADM488ARZ presents a standard unit load of 1/8, allowing up to 256 devices on a single RS-485 bus segment. In legacy 1-unit-load configurations the limit is 32 nodes. A 120 Ω termination resistor is required at each bus end, and the supply voltage must remain within 4.75 V to 5.25 V for all nodes.
What operating temperature range does ADM488ARZ cover and does it meet industrial standards?
ADM488ARZ operates from -40°C to +85°C, covering the full industrial temperature range. The device is compliant with EIA-422 and EIA-485 interface standards and accepts common-mode voltages of -7 V to +12 V, making it tolerant of the ground potential differences common in factory-floor wiring environments.
Is ADM488ARZ RoHS-compliant and what package does it use?
The ADM488ARZ is specified in the SOIC-8 package (Analog Devices code R-8, JEDEC MS-012AA outline) with a 1.27 mm lead pitch and a body measuring 4.9 mm x 3.9 mm. Note that the Pbfree code for this specific variant is listed as No; engineers requiring a lead-free SOIC-8 RS-485 transceiver should verify the current RoHS status with the distributor at time of purchase.
