AD9032BD

Overview

The AD9032BD is a 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., packaged in a 40-pin hybrid circuit. It features a subranging architecture enabling sample rates from DC to 25.6 MSPS. The device integrates on-board track-and-hold circuits, voltage references, and timing logic. Key electrical specifications include a single 3.8 W power consumption and a spurious-free dynamic range of 74 dB up to 12 MHz at the input. The bipolar input range is specified at 1.024 V.

Feature Summary

• 25.6 MSPS maximum conversion speed using subranging architecture
• Integrated on-board track-and-hold, voltage reference, and timing circuits
• 74 dB Spurious-Free Dynamic Range (SFDR) to 12 MHz input frequency
• Low power consumption of 3.8 W with single supply operation

Applications

• Radar Signal Intelligence systems
• Digital Spectrum Analyzers
• Medical Imaging equipment
• Electro-Optics applications

Procurement Notes

Verify the specific suffix 'BD' against the manufacturer's official datasheet to confirm temperature grade and package variant. Ensure the 40-pin hybrid package matches the target PCB footprint. Confirm that the 3.8 W power dissipation requirements are supported by the system thermal design.

Selection Notes

Select this component for applications requiring high-speed 12-bit digitization up to 25.6 MSPS. The integrated timing and reference reduce external component count compared to discrete solutions. Verify that the 1.024 V bipolar input range aligns with the source signal amplitude before finalizing the design.

Part Context

The AD9032 series represents early high-speed ADC technology from Analog Devices. It utilizes a flash ADC core with error correction logic and residue encoding. This family was designed to provide fast sampling rates in a compact form factor prior to the widespread adoption of JESD204B/C serial interfaces.

Replacement Considerations

Public documentation lists the AD9034 as a related model within the same product family, offering similar functionality with different speed or configuration parameters. No other direct cross-model substitutes are confirmed in the provided data.
