• High-speed 40 MSPS sampling capability
• Low power consumption for portable applications
• Single 5 V supply operation
• Parallel digital output interface

Applications

• Portable instrumentation
• Medical imaging systems
• Industrial process control
• Communications equipment

Procurement Notes

Verify the specific suffix 'JR' against official Analog Devices documentation to confirm packaging type and temperature grade. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements. Confirm availability through authorized distributors as reel quantities may vary.

Selection Notes

Select this component when a balance between speed and power efficiency is required for 8-bit resolution applications. Consider the parallel interface complexity versus serial alternatives. Evaluate system noise floor requirements against the specified SNR performance under actual operating conditions.

Part Context

This part belongs to the AD239 family of high-speed ADCs from Analog Devices. It is designed for applications requiring moderate throughput with minimal power draw. The device complements other members of the series offering different sampling rates or resolutions.

Replacement Considerations

Check for direct pin-compatible replacements within the AD239 family or newer generations from Analog Devices. Verify that alternative components meet the same 40 MSPS speed and 51 dBSNR specifications. Ensure voltage levels and interface timing remain compatible with the host system.
