Overview

The AD2S1210WDSTZRL7 is a complete 10-bit to 16-bit resolution tracking resolver-to-digital converter (RDC) with an integrated onboard programmable sinusoidal oscillator that provides sine wave excitation for resolvers. It features a specified operating temperature range of -40 degC to +125 degC and is designed for high-performance position and velocity sensing in harsh environments.

Why Choose This Part

The device offers selectable resolution from 10 to 16 bits, allowing engineers to balance tracking rate and precision within a single IC. Its wide operating temperature range and integrated excitation oscillator reduce PCB footprint and external component count in safety-critical automotive and industrial designs.

Applications

Electric Vehicle Motor Control
High-accuracy position sensing for permanent magnet synchronous motors (PMSM) and brushless DC motors in EV powertrains.
Industrial Robotic Actuation
Providing precise angular position feedback for multi-axis robotic joints and industrial motion controllers.
Automotive Electronic Power Steering
Used to monitor the steering shaft angle and motor position for electronic power steering (EPS) systems.
Integrated Starter Generators
Determining the rotor position for starter-generator units in mild-hybrid vehicle architectures.

Getting Started

Start development by interfacing the 48-LQFP package with a microcontroller via the 16-bit parallel or 3-wire serial interface. Ensure the 4.75V to 5.25V supply is well-decoupled and follow the manufacturer recommendation for the external excitation buffer circuit to drive the resolver primary winding.
