AD2S1200ZSTZ

Overview

The AD2S1200ZSTZ is a complete 12-bit resolution tracking resolver-to-digital converter manufactured by Analog Devices Inc. It integrates an on-board programmable sinusoidal oscillator to provide sine wave excitation for resolvers. The device requires an external 8.192 MHz crystal to generate a precision time reference, which is internally divided to produce a 4.096 MHz clock for peripheral operation. It operates on a single 5.00 V ± 5% supply and supports both parallel and serial data ports. The component provides absolute position and velocity outputs with differential inputs and ±11 arc minutes of accuracy.

Feature Summary

• Complete monolithic 12-bit R/D converter with integrated programmable sinusoidal oscillator
• Supports parallel and serial 12-bit data ports compatible with DSP and SPI standards
• Features system fault detection and 4 kV ESD protection
• Operates within a temperature range of -40°C to +125°C

Applications

• Servo motor control systems requiring high-precision position feedback
• Industrial automation equipment utilizing rotary encoders
• Robotics applications demanding absolute position and velocity data

Procurement Notes

Verify the specific suffix ZSTZ against official Analog Devices documentation to confirm package type and environmental compliance. Confirm availability status as distribution channels may indicate limited stock or regional restrictions. Ensure the required 8.192 MHz crystal is sourced separately as it is not included in the component package.

Selection Notes

Select this component when a fixed 12-bit resolution is sufficient for the application. The AD2S1200 family offers different pinouts and resolutions; ensure the LQFP-44 package matches the PCB layout. Compare with the AD2S1210 series if higher resolution (up to 16-bit) or automotive qualification (AEC-Q100) is required instead of the standard industrial grade found in the AD2S1200.

Part Context

The AD2S1200 belongs to the AD2S1200 series of resolver-to-digital converters. It serves as a direct interface between analog resolver sensors and digital processing units. The ZSTZ designation indicates a specific tape-and-reel packaging variant of the standard AD2S1200, distinct from tray-packaged versions like the YSTZ.

Replacement Considerations

The AD2S1200WSTZ and AD2S1200YSTZ are functionally equivalent parts within the same series, differing primarily in packaging format. For applications requiring higher resolution, the AD2S1210CSTZ or AD2S1210WDSTZ are suitable upgrades, though they utilize a 48-lead LQFP package.
