AD2S65422B

Overview

The AD2S65422B is a high-precision, single-chip resolver-to-digital converter (RDC) manufactured by Analog Devices. It converts analog sine and cosine signals from a resolver into parallel digital position data. The device features a 32-pin ceramic dual in-line package (CDIP) designed for through-hole mounting on printed circuit boards. It supports multiple resolution options including 10, 12, 14, and 16 bits, providing accurate angular position feedback for demanding industrial and aerospace applications.

Feature Summary

• Single-chip integration of resolver-to-digital conversion functions
• Supports variable resolution outputs up to 16 bits
• Robust ceramic dual in-line package construction for harsh environments

Applications

• Aerospace flight control systems
• Industrial servo motor feedback
