AD9026AD

Overview

The AD9026AD is a monolithic 12-bit analog-to-digital converter (ADC) utilizing flash conversion architecture. It features parallel access output and operates within a temperature range of -25°C to +85°C. The device accepts differential analog input voltages ranging from -1.024 V to +1.024 V, with a maximum linear error of 0.0732%. It employs offset binary output coding and is housed in a hermetically sealed ceramic CDIP-28 package measuring 0.600 inches. The component requires a nominal negative supply voltage of -5.2 V.

Feature Summary

• 12-bit resolution with flash conversion method
• Parallel word output format using offset binary coding
• Hermetically sealed ceramic DIP-28 package
• Analog input range of ±1.024 V

Applications

• High-speed data acquisition systems
• Test and measurement instrumentation
• Industrial control applications requiring precise analog digitization

Procurement Notes

Verify the specific suffix 'AD' against official Analog Devices documentation to confirm it denotes the industrial temperature grade (-25°C to +85°C) and ceramic package variant. Ensure compliance requirements are met, as the component is noted as non-RoHS compliant in available records. Confirm pinout compatibility with target PCB layouts for the 0.600-inch CDIP-28 footprint.

Selection Notes

Select this component when a 12-bit resolution and parallel interface are required for high-speed sampling. Consider the hermetic ceramic package if environmental sealing or radiation hardness is necessary. Verify that the system can accommodate the ±1.024 V input range and the specific -5.2 V negative supply requirement. Compare performance metrics such as linearity and speed against other ADC families if digital serial interfaces are preferred over parallel outputs.

Part Context

The AD9026 series represents Analog Devices' offering in the high-performance flash ADC market. The AD9026AD specifically refers to the version packaged in a ceramic dual in-line package suitable for demanding environments. This part differs from plastic-packaged variants primarily in material construction and sealing properties, catering to applications where standard commercial packaging is insufficient.

Replacement Considerations

Direct replacements must match the 12-bit flash architecture, parallel output interface, and CDIP-28 package dimensions. Verify electrical parameters including input voltage range and supply requirements. Cross-reference with other ADI flash ADCs or competitors offering similar hermetic packages.
