AD9032AD

Overview

The AD9032AD is a 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., featuring a conversion speed of up to 25.6 MSPS. It utilizes a subranging converter architecture to achieve sample rates from DC to 25.6 MSPS. The device integrates on-board track-and-hold circuits, voltage references, and timing circuits within a single 40-pin package. Key electrical specifications include a spurious-free dynamic range of 74 dB at 12 MHz input frequency and a bipolar input voltage range of 1.024 V. The component operates with a power consumption of 3.8 W.

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) up to 12 MHz input frequency
• Bipolar analog input range of 1.024 V
• Single 40-pin package design

Applications

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

Procurement Notes

Verify the specific suffix 'AD' against the manufacturer's official datasheet to confirm pinout compatibility and temperature grade. Ensure that the system power supply meets the 3.8 W dissipation requirement and that the host interface supports the digital output format specified in the functional block diagram. Cross-reference the part number with current Analog Devices documentation to confirm availability status.

Selection Notes

Select this component for applications requiring high-speed 12-bit digitization up to 25.6 MSPS with integrated timing and reference circuitry. Consider the 74 dB SFDR specification when designing for signals near 12 MHz. Evaluate the 3.8 W power consumption against thermal management capabilities in the target enclosure. Compare against the AD9034 if lower sampling rates or different packaging options are required.

Part Context

The AD9032 belongs to the AD903x family of high-speed data converters. It is positioned as a fast 12-bit ADC solution, distinct from lower-speed or higher-resolution variants in the Analog Devices portfolio. The device serves as a standalone converter, differing from integrated RF transceivers like the AD9361 series which combine ADC/DAC functions with RF front-ends.

Replacement Considerations

The AD9034 is a related model offering similar functionality with a maximum sample rate of 20 MSPS. Verify pin compatibility and performance trade-offs before substitution.
