What this instrumentation amp does and where it fits
The AD8428ARZ is a single instrumentation amplifier in an 8-SOIC package.
50 V/µs slew rate and 3.5 MHz bandwidth — what they mean for signal fidelity
The 50 V/µs slew rate and 3.5 MHz bandwidth support high-speed sensor conditioning.
Supply range and output drive — sizing the rail and load
The 8 V to 36 V supply span and 30 mA output per channel suit industrial rails.
Active lifecycle — no obsolescence watch needed
The AD8428ARZ carries an Active product status, so there is no last-time-buy clock ticking. This part is still in Analog Devices' current catalog and can be designed into a new BOM without an obsolescence risk flag. The ROHS3 compliance means it meets the EU RoHS exemption-free standard — no need for an exemption review in your compliance database. For a BOM freeze, this is a low-risk line item: no PCN watch, no end-of-life paperwork to track.
Package and marking — what to expect on the tube
The AD8428ARZ ships in a Tube. The 8-SOIC body is 3.90 mm wide.
