AD9032TD

Overview

The AD9032TD is a high-speed 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a subranging architecture to achieve sampling rates up to 25.6 MSPS, incorporating on-board track-and-hold circuits, voltage references, and timing logic. The device is housed in a 40-pin hybrid ceramic package designed for robust performance. Key electrical specifications include a spurious-free dynamic range of 74 dB at a 12 MHz input frequency and support for bipolar inputs with a swing of 1.024 V. The component operates with a single power supply consuming approximately 3.8 W.

Feature Summary

Procurement Notes

Verify the specific suffix 'TD' against official Analog Devices documentation to confirm pinout compatibility and material compliance. Ensure that the 40-pin hybrid ceramic package matches the target PCB footprint requirements. Cross-reference the datasheet revision date to validate the accuracy of the 25.6 MSPS sampling rate and 3.8 W power consumption figures before finalizing procurement specifications.

Selection Notes

Select the AD9032TD when a 12-bit resolution and sampling speeds approaching 25.6 MSPS are required within a single integrated package. The inclusion of internal timing and reference circuits reduces external component count compared to discrete solutions. Consider the 1.024 V bipolar input range and 74 dB SFDR performance metrics to ensure alignment with signal integrity requirements in radar or spectrum analysis designs.

Part Context

The AD9032TD belongs to the AD9032 family of high-performance data converters. This series was historically positioned as a leading solution for fast 12-bit conversion tasks. The 'TD' designation typically indicates a specific thermal or packaging variant within the broader AD9032 product line, sharing the core functional block diagram and subranging architecture with standard AD9032 units.

Replacement Considerations

Publicly confirmed substitute part numbers for the AD9032TD are not available in the provided source material. Engineers should consult current Analog Devices catalogs for newer generation ADCs with comparable sampling rates and bit resolutions.
