AD2S1000YSTZ

Overview

The AD2S1000YSTZ is a high-precision resolver-to-digital converter manufactured by Analog Devices Inc. It provides 12-bit resolution for angular position and velocity measurements. The device operates on a single 5 V power supply and supports both parallel and serial digital interfaces. It features an integrated reference oscillator to drive the resolver excitation input. The component is housed in a 44-lead LQFP package and is rated for operation within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a programmable sine wave oscillator for direct resolver excitation
• Provides high-resolution tracking conversion from analog resolver signals to digital data
• Supports flexible system integration through selectable parallel or serial output interfaces

Applications

• Motor control systems requiring absolute shaft position feedback
• Industrial automation equipment needing precise rotational measurement
• Robotics applications utilizing servo motor feedback loops

Procurement Notes

Verify the specific suffix YSTZ against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the design accounts for the required 5 V supply voltage and interface selection logic. Confirm that the LQFP-44 thermal characteristics meet the application's heat dissipation requirements.

Selection Notes

Select this component when a dedicated hardware solution for resolver demodulation is preferred over software-based DSP processing. It is suitable for designs requiring fixed 12-bit resolution without the complexity of higher-speed ADCs. Consider the available evaluation board resources for initial circuit validation and interface timing verification.

Part Context

This part belongs to the AD2S1000 family of resolver-to-digital converters, designed for robust performance in noisy environments. It serves as a specialized data acquisition component distinct from general-purpose ADCs, focusing specifically on decoding sinusoidal differential signals from electromagnetic resolvers.

Replacement Considerations

The AD2S1200 offers similar functionality with 12-bit resolution but includes an internal reference oscillator, potentially simplifying external circuitry. Verify pin compatibility and interface differences before substitution.
