Description

The AD2S80AAD is a monolithic tracking resolver-to-digital converter that features a 10-, 12-, 14-, or 16-bit resolution, and it is contained in a 40-lead DIP or 44-terminal LCC ceramic package. The converter is manufactured in a BiMOS II process that combines the advantages of CMOS logic and bipolar high accuracy linear circuits on the same chip. It is designed to enable users to select their own resolution and dynamic performance with external components, allowing them to define the best converter that meets their system requirements. The converter can track resolver signals that rotate at up to 1040 revs per second when set to 10-bit resolution.

Application Scenarios

The AD2S80AAD is commonly used in the following applications:

• DC Brushless and AC Motor Control
• Process Control
• Numerical Control of Machine Tools
• Robotics
• Axis Control
• Military Servo Control

Comparison

• The resolver-to-digital converter allows users to select their preferred resolution and dynamic performance options through external components, which provides more flexibility.
• It features high-noise immunity and tolerance of lead length when the converter is remote from the resolver due to its ratiometric tracking conversion method.

• The AD2S80AAD may not be suitable for applications that require a greater resolution than the maximum of 16-bits.
