Product details
Overview
AD9032AZ from Analog Devices is a 12-bit, 25.6 MSPS ECL-compatible analog-to-digital converter with on-board track-and-hold, voltage references, and timing circuits. It delivers 74 dB spurious-free dynamic range (SFDR) to 12 MHz input frequency, ±1.024 V bipolar analog input range, and operates from +5 V and –5.2 V supplies in a 40-pin ceramic leaded chip carrier (Z-40) package. It is used in radar and digital spectrum analyzers requiring high-speed, high-dynamic-range digitization.
For engineers reviewing the AD9032AZ datasheet, AD9032AZ pinout, AD9032AZ application, or AD9032AZ equivalent, key selection criteria include ECL-level digital output compatibility, aperture jitter ≤8 ps rms, 12-bit monotonicity with no missing codes, industrial temperature range (–25°C to +85°C), and hybrid-package thermal management for 3.8 W power dissipation.
Technical Context
The AD9032AZ employs a digitally corrected subranging architecture comprising a monolithic track-and-hold (AD9101), 5-bit flash ADC, 14-bit DAC, summation amplifier with clamping, and 8-bit flash ADC for residue conversion. This structure enables 25.6 MSPS sampling while maintaining 64 dB SNR at 12.1 MHz input.
Its timing is factory-trimmed and synchronized to differential ECL encode inputs; data-ready output provides precise latching control with 7.5 ns typical delay. All digital outputs are ECL-compatible (–1.1 V / –1.5 V logic levels), use 2's complement coding, and require external 510 Ω termination to –5.2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - guarantees monotonic transfer function with no missing codes across full operating temperature range. |
| Sample Rate | 25.6 MSPS - maximum sustained conversion rate enabling real-time digitization of IF signals up to 12 MHz bandwidth. |
| SFDR | 74 dBc @ 12 MHz AIN - defines usable dynamic range before strongest spurious tone limits signal detection sensitivity. |
| Analog Input Range | ±1.024 V - factory-trimmed bipolar range optimized for compatibility with AD9034 evaluation infrastructure. |
| Aperture Uncertainty | ≤8 ps rms - directly limits SNR degradation at high input frequencies; critical for coherent radar processing. |
| Power Dissipation | 3.8 W typical - requires thermal design with θCA ≤13°C/W in still air or active airflow/heat sink for sustained operation. |
| Supply Voltages | +5.0 V and –5.2 V - dual-rail ECL-compatible supply set enabling direct interface with ECL logic without level translation. |
Pinout & Package
The AD9032AZ is housed in a 40-pin ceramic leaded chip carrier (Z-40) package with leads unformed at shipment; pin 1 identified by notch or dot. Package dimensions: 1.900" × 1.090" × 0.205" (48.26 mm × 27.69 mm × 5.21 mm), compatible with standard hybrid assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Gain Adjust / Offset Adjust | Vernier calibration inputs (20 kΩ impedance); unused in standard operation but enable ±10 mV offset / ±20 mV gain trim without degrading dynamic performance. |
| 3, 5, 6, 14, 21, 22, 35, 40 | GROUND | Low-impedance analog/digital return paths; must be tied together and connected to solid ground plane near device to minimize noise coupling. |
| 4 | Analog Input | ±1.024 V bipolar input with 100 Ω resistance and 7 pF capacitance; requires impedance-matched layout and isolation from digital traces. |
| 10 | Overflow | ECL output asserted high when analog input exceeds +FS; used for saturation detection in real-time signal monitoring. |
| 11 | Data Ready | ECL output with rising edge timed 7.5 ns after data valid; provides synchronous latch trigger for external ECL registers. |
| 12, 17, 20, 38 | –VS | –5.2 V supply pins; each requires local 0.1 µF ceramic + 10 µF tantalum decoupling to ground to suppress switching noise. |
| 13, 39 | +VS | +5.0 V supply pins; same decoupling requirements as –VS; shared analog/digital rail simplifies power delivery. |
| 18, 19 | Encode / Encode | Differential ECL clock inputs; sampling occurs on rising edge; no internal termination-external 510 Ω termination required. |
| 23–34 | D0–D11 | ECL-compatible 12-bit 2's complement digital outputs; D0 = LSB, D11 = MSB; require 510 Ω pull-down to –5.2 V for valid logic levels. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold | Monolithic AD9101 T/H enables accurate sampling of high-slew-rate signals up to 220 MHz analog bandwidth without external components. |
| Integrated voltage references | Factory-trimmed internal references eliminate need for external precision references and reduce board area/cost in radar front ends. |
| Digital error correction | Subranging + residue correction ensures 12-bit linearity (≤1.0 LSB INL) and guaranteed no missing codes across temperature. |
| ECL-compatible I/O | Direct interface with ECL logic families avoids level-shifting delays and jitter, preserving timing integrity in high-speed acquisition systems. |
| Hybrid packaging | Ceramic leaded chip carrier (Z-40) provides hermetic sealing, stable thermal resistance (θCA = 13°C/W), and compatibility with military-grade PCB assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9034AR | 20 MSPS max sample rate; identical Z-40 package and pinout; shares same evaluation board (AD9034/PCB). | Lower throughput suitable for cost-sensitive spectrum analyzers where 25.6 MSPS is not required. | Select AD9034AR when system clock budget or power envelope restricts to ≤20 MSPS operation. |
| AD9220AR | 12-bit, 10 MSPS; CMOS outputs; single +5 V supply; SOIC-28 package; no on-chip T/H or references. | Requires external T/H, reference, and level-shifting for ECL interface; suited for lower-frequency embedded instrumentation. | Choose AD9220AR only if board space, supply simplicity, or legacy CMOS interface outweigh need for integrated signal chain. |
Compared with AD9032AZ, AD9034AR offers identical form-factor and evaluation support at reduced speed, while AD9220AR trades integration and performance for lower cost and simpler power architecture-neither is pin-compatible, and both require redesign of analog front end and digital interface.

FAQ
What is the operating temperature range for the AD9032AZ?
The AD9032AZ is rated for industrial temperature operation from –25°C to +85°C. This range is validated across all electrical specifications including DC accuracy, dynamic performance, and timing parameters. The device uses a ceramic leaded chip carrier (Z-40) package engineered for thermal stability under these conditions, and its 3.8 W power dissipation requires appropriate heatsinking or airflow to maintain case temperature ≤85°C for guaranteed performance.
Does the AD9032AZ require external voltage references or a track-and-hold amplifier?
No, the AD9032AZ does not require external voltage references or a track-and-hold amplifier. It integrates on-chip precision voltage references and a monolithic track-and-hold (AD9101) circuit, enabling full 12-bit performance with only analog input, differential ECL encode clock, and dual power supplies (+5 V and –5.2 V). This integration reduces bill-of-materials count and PCB area in radar and spectrum analyzer designs where the AD9032AZ is deployed.
What are the power supply requirements for the AD9032AZ?
The AD9032AZ requires two supplies: +5.0 V (±5%) at up to 160 mA and –5.2 V (±5%) at up to 672 mA, resulting in typical power dissipation of 3.8 W. Each supply pin must be decoupled with a 0.1 µF ceramic capacitor and a 10 µF tantalum capacitor to ground. Linear supplies are recommended for optimal dynamic performance; if switching supplies are used, low-frequency ripple (<1 MHz) and strict decoupling per the AD9032AZ datasheet are mandatory to avoid SNR degradation.
Is the AD9032AZ pin-compatible with other members of the AD903x family?
Yes, the AD9032AZ is pin-compatible with the AD9034AR and AD9032AR variants in the same Z-40 package. All share identical pin assignments for analog input, encode, data outputs, power, and ground. However, the AD9032AZ operates at 25.6 MSPS while the AD9034AR is limited to 20 MSPS; this difference affects timing margins and maximum input bandwidth but not physical layout or interconnect.
What evaluation resources are available for the AD9032AZ?
An evaluation board originally designed for the AD9034 (part number AD9034/PCB) is fully compatible with the AD9032AZ due to pin compatibility. The board includes a reconstruction DAC, analog input amplifier, and digital output interface, and measures 7.25" × 6". Schematics and layout files are provided in the AD9034 datasheet. No separate AD9032AZ-specific evaluation hardware is offered; users order the AD9034/PCB board and mount the AD9032AZ in the designated socket or footprint.
