Product details
Overview
AD9058ATD/883B from Analog Devices is a dual 8-bit, 50 MSPS analog-to-digital converter (ADC) in a hermetic 48-lead SBDIP package, rated for –55°C to +125°C operation. It integrates two matched ADCs with on-board 2 V voltage reference, TTL-compatible digital I/O, and low input capacitance (10 pF), designed for high-reliability quadrature receiver systems in radar and electronic warfare.
For engineers reviewing the AD9058ATD/883B datasheet, AD9058ATD/883B pinout, AD9058ATD/883B application, or AD9058ATD/883B equivalent, key selection criteria include military-grade temperature range, aperture delay matching (≤0.5 ns), ENOB of 7.4 bits at 10.3 MHz, crosstalk rejection ≥48 dBc, and compatibility with ±5 V analog supplies and TTL logic levels.
Technical Context
The AD9058ATD/883B employs a patented interpolating architecture using 128 comparators per ADC-half that of a conventional flash converter-enabling reduced input capacitance (10 pF) and die size while maintaining 8-bit resolution. Each ADC operates independently with separate analog inputs, encode clocks, and reference ladders.
It supports unipolar 0 V to 2 V operation via internal +VINT (2 V bandgap reference), or bipolar ±1 V operation with external references. Aperture uncertainty is 10 ps rms, and propagation delay tempco is –16 ps/°C, ensuring stable timing across its full military temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - fixed quantization depth enabling direct interface with 8-bit data buses and legacy DSPs. |
| Max Conversion Rate | 50 MSPS - supports real-time digitization of IF signals up to 175 MHz analog bandwidth. |
| ENOB @ 10.3 MHz | 7.4 bits - indicates usable dynamic range of ~44 dB SNR in communications-band signal acquisition. |
| Input Capacitance | 10 pF - minimizes loading on preceding amplifiers (e.g., AD9617/AD9618) in high-Z signal chains. |
| Aperture Delay Matching | ≤0.5 ns - ensures precise I/Q channel alignment critical for quadrature demodulation fidelity. |
| Crosstalk Rejection | ≥48 dBc - prevents spectral leakage between ADC-A and ADC-B when sampling independent RF paths. |
| Supply Voltages | +VS = +5 V, –VS = –5 V - dual-rail analog supply enables true bipolar input support with external references. |
Pinout & Package
AD9058ATD/883B is housed in a hermetic 48-lead side-brazed ceramic dual in-line package (SBDIP, D-48), qualified per MIL-STD-883 for high-reliability military applications. The package features low thermal resistance (θJC = 12°C/W) and gold metallization for long-term stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 40 | GROUND (Analog/Digital) | Common return for analog and digital sections; must be connected to single low-impedance ground plane. |
| 5, 9, 22, 24, 37, 41 | +VS | +5 V analog and digital supply; requires local 0.1 µF ceramic bypassing to ground. |
| 7, 20, 26, 39 | –VS | –5 V analog supply; clamping diode recommended if +VS powers before –VS to prevent latch-up. |
| 6, 43 | +VREF | Top of internal reference ladder; sets upper bound of analog input range (e.g., +2 V for unipolar mode). |
| 8, 38 | –VREF | Bottom of internal reference ladder; sets lower bound (e.g., 0 V for unipolar, –1 V for bipolar). |
| 17, 8 | AIN (A/B) | Dedicated analog inputs for Channel A and Channel B; each accepts 0 V–2 V or ±1 V differential range. |
| 23, 2 | ENCODE | TTL-compatible sample clock input; rising edge triggers simultaneous conversion on both ADCs. |
| 25–32, 47–42 | D0–D7 (A/B) | TTL-level digital outputs (LSB to MSB); require 2 kΩ pull-down resistors for reliable latching above 40 MSPS. |
| 12 | +VINT | Internal 2 V bandgap reference output; drives both ADC reference ladders without external components. |
| 13 | COMP | Compensation node for external 0.1 µF capacitor to stabilize internal reference loop dynamics. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched ADCs on single die | Guarantees <0.5 ns aperture delay matching and >48 dBc crosstalk rejection for coherent I/Q sampling. |
| Interpolating architecture | Reduces comparator count to 128 per ADC, cutting input capacitance to 10 pF and easing driver amplifier design. |
| On-board 2 V bandgap reference (+VINT) | Drives both ADC reference ladders simultaneously, eliminating need for external reference ICs in unipolar systems. |
| Military temperature qualification | Rated –55°C to +125°C and tested per MIL-STD-883, supporting deployment in avionics, radar, and EW platforms. |
| TTL-compatible I/O | Accepts standard 0.8 V / 2.0 V logic thresholds and sources/sinks 2 mA, interfacing directly with 74ACT/74HCT logic families. |
Applications
| Quadrature Demodulation | Digital Oscilloscopes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9057ATD/883B | Single 8-bit, 50 MSPS ADC in same D-48 package; no second channel or I/Q matching. | Suitable only for non-coherent single-path digitization; lacks aperture matching and crosstalk specs. | Select when system requires only one ADC channel and space/power constraints favor reuse of AD9058 footprint. |
| AD9220ASTZ-50 | Single 10-bit, 50 MSPS ADC in 48-lead LQFP; higher resolution but no integrated reference or military temp grade. | Used in commercial test equipment where 10-bit ENOB outweighs need for I/Q coherence or extended temperature operation. | Choose for improved dynamic range in benign environments; not drop-in replaceable due to different package, pinout, and reference architecture. |
Compared with AD9058ATD/883B, AD9057ATD/883B reduces channel count and eliminates I/Q synchronization capability, while AD9220ASTZ-50 trades military reliability and dual-channel integration for higher resolution in commercial applications-neither offers pin-compatible replacement or guaranteed aperture matching.

FAQ
What is the operating temperature range of the AD9058ATD/883B?
The AD9058ATD/883B is specified for continuous operation from –55°C to +125°C and qualified per MIL-STD-883, making it suitable for deployment in avionics, missile guidance, and ground-mobile electronic warfare systems where ambient extremes are common. This rating applies specifically to the /883B military screening variant, not commercial versions like AD9058AJD.
Does the AD9058ATD/883B include an internal voltage reference?
Yes, the AD9058ATD/883B integrates a 2 V bandgap voltage reference (+VINT) capable of driving both internal reference ladders. When used with +VREF and –VREF pins tied appropriately, this enables unipolar 0 V to 2 V analog input operation without external reference components-confirmed in the Functional Block Diagram and General Description sections of the datasheet.
What package type is used for the AD9058ATD/883B?
The AD9058ATD/883B uses a hermetic 48-lead side-brazed ceramic dual in-line package (SBDIP, package option D-48). Its mechanical outline, lead finish (gold), and thermal characteristics (θJC = 12°C/W) are fully documented in the Ordering Guide and Outline Dimensions section of the AD9058 datasheet Rev. E.
How is aperture delay matching specified for the AD9058ATD/883B?
Aperture delay matching for the AD9058ATD/883B is guaranteed ≤0.5 ns across temperature (Test Level IV), measured between Channel A and Channel B under identical conditions. This parameter is explicitly listed in the ELECTRICAL CHARACTERISTICS table and is critical for preserving phase integrity in quadrature receiver architectures.
Can the AD9058ATD/883B operate with external voltage references?
Yes, the AD9058ATD/883B supports external references applied to +VREF and –VREF pins, enabling flexible input ranges including ±1 V bipolar operation. Figure 3 in the datasheet shows a verified implementation using AD580 and discrete op-amps; the internal +VINT reference is disabled in this configuration, and reference ladder offset specifications apply.
