AD2S80AAD

AD2S80AAD is a resolver-to-digital converter from Analog Devices in a 40-lead side-brazed ceramic DIP (SBDIP-40) — the D-grade orderable of the AD2S80A, specified at 8 arc minutes accuracy over -40 °C to +85 °C. Resolution is user-selectable at 10, 12, 14 or 16 bits, and the part runs from dual supplies of ±10.8 V to ±13.2 V, converting resolver position feedback into digital angle data for servo drives, antenna positioning and legacy motion-control systems. Lifecycle honesty: Analog Devices lists the AD2S80A as NOT RECOMMENDED FOR NEW DESIGNS (NRND), and this code is a leaded part that is not RoHS compliant — it belongs in sustainment, repair and already-qualified legacy builds, not in new designs; for a new resolver interface, evaluate current-production converters instead. The AD2S80A datasheet ordering guide (Rev. D) lists this exact code. Parameters verified against Analog Devices documentation.
