ad2s80a is a variable resolution, monolithic resolver-to-digital converter from analog devices.
The AD2S80A is a monolithic resolver‑to‑digital converter available in 40‑lead DIP and 44‑terminal LCC packages. It offers user‑selectable resolution (10‑, 12‑, 14‑ or 16‑bit) and dynamic performance set by external components, with low power consumption (≈300 mW) and a high maximum tracking rate of 1040 rps at 10‑bit resolution.
The device includes a velocity analog output, ratiometric tracking conversion, and ESD Class 2 protection. It operates over a wide temperature range (commercial to military) and is supplied with detailed pin configurations, recommended external components, and connection diagrams for resolver integration.
