• Integrated reference voltage generation for simplified external circuitry
• Capable of direct conversion between analog voltage signals and digital pulse frequencies

Applications

• Precision analog-to-digital signal digitization systems
• Isolated data transmission via optical or magnetic coupling
• Industrial instrumentation requiring high-resolution frequency outputs

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and reel configuration. Confirm RoHS compliance status as availability varies by production batch. Ensure the ordering part number matches the required lead frame finish and moisture sensitivity level specifications before finalizing procurement orders.

Selection Notes

Select this component when high linearity and low temperature drift are critical requirements for voltage-to-frequency conversion tasks. Evaluate the need for external clock synchronization capabilities to determine if this synchronous model is superior to asynchronous alternatives. Consider the 20-PLCC package constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability.

Part Context

This device belongs to the AD652 family of precision data converters designed for demanding industrial applications. It serves as a core building block for systems requiring accurate analog signal processing without intermediate digital stages.
