**AD2S99BP: The High-Performance Resolver-to-Digital Converter for Precision Motion Control Systems**
In the realm of precision motion control, the accurate measurement of angular position and velocity is paramount. Systems ranging from industrial robotics and CNC machinery to aerospace actuation and advanced servo drives demand unwavering reliability and exceptional accuracy. At the heart of many such systems lies a critical component: the resolver-to-digital converter (RDC). The **AD2S99BP**, a high-performance monolithic converter from Analog Devices, stands as a premier solution engineered to meet these rigorous demands.
A resolver is an analog sensor that outputs sinusoidal signals representing the sine and cosine of the shaft angle. Its rugged, all-metal construction makes it inherently resistant to harsh environments—including extreme temperatures, dust, and moisture—where optical encoders might fail. However, translating the resolver's analog outputs into a precise, noise-immune digital representation requires a sophisticated interface. This is the exact function of the **AD2S99BP**.
The **AD2S99BP excels through its type II tracking loop architecture**, which continuously tracks the input angle and velocity. This closed-loop system offers significant advantages over open-loop conversion methods, providing **exceptional noise rejection** and maintaining accuracy even in the presence of signal harmonics, corrupting noise, or rapid changes in velocity. The device accepts a resolver format input and directly provides a 10-bit or 12-bit digital word parallel output, alongside a velocity output, with minimal external component requirements.
Key performance characteristics that define the AD2S99BP's superiority include its **high accuracy and reliability across a wide range of operating conditions**. It features a maximum tracking rate of 1,200 rps at 10-bit resolution, making it suitable for high-speed applications. Its integrated on-board programmable sinusoidal oscillator provides the excitation signal for the resolver, simplifying system design and enhancing overall stability. Furthermore, the converter is designed to be highly fault-resilient, with built-in detection for critical errors such as resolver wire breaks, loss of input signals, or out-of-range inputs, thereby ensuring system safety and integrity.
The implementation of the AD2S99BP significantly reduces design complexity and board space while improving system robustness. By providing a seamless, high-fidelity digital interface for resolvers, it enables designers to build motion control systems that are both precise and durable, capable of operating in the most challenging conditions.
