Product details
Overview
AD9002SD/883B from Analog Devices is a military-grade, 8-bit monolithic analog-to-digital converter with 0.75 LSB differential linearity, 150 MSPS encode rate, and 160 MHz large-signal analog input bandwidth. It operates on a –5.2 V single supply, delivers 750 mW nominal power dissipation, and features ECL-compatible outputs with overflow indication-designed for radar warning receivers and electronic warfare signal acquisition.
For engineers reviewing the AD9002SD/883B datasheet, AD9002SD/883B pinout, AD9002SD/883B application, or AD9002SD/883B equivalent, this page provides verified technical context, MIL-STD-883B-compliant package details, real-world timing behavior (1.3 ns aperture delay, 15 ps jitter), and validated alternatives for high-speed sampling in extended-temperature defense systems.
Technical Context
The AD9002SD/883B implements a flash architecture with 256 parallel comparators and ECL-compatible output latches, enabling full 8-bit conversion on each rising edge of the differential ENCODE signal. Its comparator design incorporates user-adjustable hysteresis (0–10 mV via HYSTERESIS pin) and an overflow inhibit function to control overrange response polarity.
It uses a resistor ladder reference network with +VREF, –VREF, and REFMID pins, supporting 2.0 V differential reference voltage. Input bias current is 60–200 µA, input capacitance is 17 pF, and analog input slew rate is 440 V/µs-enabling direct sampling of fast pulses without external track-and-hold circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - delivers discrete quantization levels for digital signal processing of RF and pulse waveforms. |
| Encode Rate | 150 MSPS - supports real-time digitization of wideband signals up to Nyquist frequency of 75 MHz. |
| Differential Linearity | 0.75 LSB (max, full temperature range) - ensures monotonicity and minimizes code-width variation across all 256 codes. |
| Analog Input Bandwidth | 160 MHz - enables accurate capture of fast transients and high-frequency modulation without aliasing or settling error. |
| Aperture Uncertainty | 15 ps - limits sampling-time jitter-induced SNR degradation to ≤0.5 dB at 10 MHz input. |
| Power Dissipation | 750 mW at –5.2 V - compatible with conduction-cooled military chassis and thermally constrained embedded modules. |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883B Class B for airborne, missile, and ground vehicle electronics. |
Pinout & Package
AD9002SD/883B is packaged in a 28-lead side-brazed ceramic dual in-line package (SBDIP, D-28), hermetically sealed and qualified for military extended-temperature operation. The package features four digital ground pins, two analog ground pins, dual analog and digital –VS supply connections, and dedicated reference and hysteresis control terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13, 20, 23 | DIGITAL GROUND | Low-impedance return path for ECL output switching currents; must be tied together and connected to system digital ground at single point near device. |
| 2 | OVERFLOW INH | Controls polarity of OVERFLOW output and data bus state during overrange inputs; logic low = non-return-to-zero mode, floating at –5.2 V = return-to-zero mode. |
| 3 | HYSTERESIS | Adjusts comparator hysteresis from 0 to 10 mV by applying –5.2 V to –2.2 V; improves noise immunity in high-EMI environments. |
| 4, 11, 12 | +VREF / –VREF / REFMID | Three-point reference interface for internal 40–110 Ω resistor ladder; enables precise offset and gain calibration and integral linearity correction. |
| 5, 10 | ANALOG INPUT | Differential analog input pair; requires matched trace lengths and symmetric drive to maintain <1.3 ns aperture delay matching. |
| 7, 8 | ENCODE / ENCODE | Differential ECL clock input; data latched on rising edge; requires <10 ns rise/fall time and proper termination to –2 V. |
| 15–19, 24–26 | D1(LSB) to D8(MSB) | ECL-compatible 8-bit parallel output bus; all outputs delayed by tPD (2.5–5.5 ns) and skewed ≤0.6 ns bit-to-bit. |
| 27 | OVERFLOW | Active-high flag indicating AIN > +VREF; asserted synchronously with data outputs and subject to same timing delays. |
Key Features
| Feature | Design Value |
|---|---|
| Flash ADC Architecture | 256 parallel comparators with fault-tolerant decoding logic eliminate missing codes and minimize false-code generation at 150 MSPS. |
| MIL-STD-883B Compliance | Class B screening includes temperature cycling, mechanical shock, vibration, and burn-in-ensuring reliability in mission-critical platforms. |
| Low Input Capacitance | 17 pF enables direct interface with wideband amplifiers (e.g., AD9610) without bandwidth-limiting external matching networks. |
| Overflow Control Logic | Dual-mode overrange handling (return-to-zero or non-return-to-zero) allows flexible data processing in pulse-detection and thresholding applications. |
| Adjustable Comparator Hysteresis | 0–10 mV programmable hysteresis via external voltage on HYSTERESIS pin improves dynamic performance in noisy RF front-end environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed sampling applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9002TD/883B | 0.5 LSB differential linearity vs. 0.75 LSB; otherwise identical electrical specs, package, and MIL-STD-883B qualification. | Suitable where tighter DC linearity is required for calibration-sensitive measurement systems, not just detection. | Select AD9002TD/883B only if system-level testing confirms 0.5 LSB is necessary; AD9002SD/883B offers lower cost and equal dynamic performance. |
| AD9042BRUZ | 12-bit, 41 MSPS, CMOS output, 3.3 V supply; no MIL-STD-883B option; 100 mA supply current vs. 175 mA. | Used in commercial test equipment and communications baseband where resolution > speed; lacks military temp range and ECL drive. | AD9002SD/883B remains mandatory for defense applications requiring extended temperature, radiation-hardened packaging, and ECL interfacing. |
Compared with AD9002TD/883B, AD9002SD/883B trades 0.25 LSB linearity for broader availability and lower unit cost while retaining identical timing, bandwidth, and environmental specs; versus AD9042BRUZ, it delivers 3.6× higher sample rate and military qualification at the expense of resolution and modern CMOS compatibility.

FAQ
What is the maximum operating temperature range for the AD9002SD/883B?
The AD9002SD/883B is rated for continuous operation from –55°C to +125°C and is fully qualified per MIL-STD-883B Class B. This range is confirmed in the Ordering Guide and Absolute Maximum Ratings table, and applies to the ceramic DIP package used for this variant. The AD9002SD/883B maintains specified DC accuracy and dynamic performance across this full range without derating.
Does the AD9002SD/883B require external termination for its ECL outputs?
Yes, the AD9002SD/883B ECL outputs must be terminated to –2 V through 100 Ω resistors, as explicitly stated in the Electrical Characteristics table footnote 4 and Application Information section. Improper termination causes signal reflection, increased output skew (>0.6 ns), and degraded timing margins-especially critical at 150 MSPS operation.
How does the HYSTERESIS pin affect performance of the AD9002SD/883B?
The HYSTERESIS pin on the AD9002SD/883B adjusts comparator hysteresis from 0 mV to 10 mV by applying a voltage from –5.2 V to –2.2 V. This reduces sensitivity to noise-induced false triggering, particularly in high-EMI environments like radar front-ends. Data sheet Figure 4 and Functional Description confirm hysteresis directly modulates comparator decision thresholds without affecting linearity or encode timing.
Is the AD9002SD/883B pin-compatible with other AD9002 variants?
Yes, all AD9002 variants-including AD9002SD/883B, AD9002TD/883B, AD9002AD, and AD9002AJ-share identical 28-pin DIP or JLCC footprints and pin functions. The Pin Designations table and mechanical drawings confirm consistent pin numbering and signal mapping across grades. Only the linearity specification and temperature range differ between variants.
What is the purpose of the REFMID pin on the AD9002SD/883B?
The REFMID pin on the AD9002SD/883B provides access to the midpoint tap of the internal resistor ladder, enabling fine adjustment of reference symmetry to correct integral linearity errors caused by ladder mismatches. As described in Layout Suggestions and Functional Description, injecting a small trim voltage at REFMID improves INL without altering full-scale range or requiring external components.
