Product details
Overview
AD9058AJD from Analog Devices is a dual 8-bit, 50 MSPS analog-to-digital converter (ADC) in a hermetic 48-lead SBDIP package, optimized for quadrature receiver applications requiring matched channel performance, low input capacitance (10 pF), and on-board 2 V reference support. It operates over 0°C to 70°C with ±5 V supplies and delivers 7.7 ENOB at 2.3 MHz for communications-grade signal digitization.
For engineers reviewing the AD9058AJD datasheet, AD9058AJD pinout, AD9058AJD application, or AD9058AJD equivalent, this page provides verified technical context, real-world timing behavior, dual-channel crosstalk rejection (60 dBc), TTL-compatible digital outputs, and validated alternatives for radar, electronic warfare, and digital oscilloscope designs.
Technical Context
The AD9058AJD implements a patented interpolating architecture-using only 128 comparators per ADC instead of 256-to reduce die size, input capacitance, and power while maintaining 8-bit resolution. Each ADC operates independently with separate analog inputs, encode clocks, and reference ladders.
It features an internal bandgap voltage reference (+VINT = 2.0 V typ.) capable of driving both ADC reference ladders simultaneously, enabling unipolar 0 V to 2 V operation without external components. Aperture uncertainty is 10 ps rms, and aperture delay matching between channels is ≤0.5 ns, critical for I/Q sampling fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - fixed quantization depth for consistent LSB step size (7.8 mV at 2 V full-scale) |
| Max Conversion Rate | 50 MSPS - guaranteed sample rate with SNR degradation ≤3 dB at 2.3 MHz input |
| ENOB @ 2.3 MHz | 7.7 bits - effective dynamic resolution under real-world sinusoidal excitation |
| Input Capacitance | 10 pF - enables high-impedance analog front-end design with minimal loading |
| Crosstalk Rejection | 60 dBc - isolation between ADC-A and ADC-B when driven with 2.3/3.5 MHz signals |
| Aperture Delay Matching | ≤0.5 ns - ensures sub-10 ps timing skew between I/Q sampling instants |
| Power Dissipation | 770–960 mW - total for both channels at full operating temperature range |
Pinout & Package
AD9058AJD is housed in a hermetic 48-lead side-brazed ceramic dual in-line package (SBDIP, package option D-48), rated for 0°C to 70°C operation with θJA = 40°C/W and θJC = 12°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 40 | GROUND | Analog ground return common to both ADCs; must connect to low-impedance ground plane |
| 3, 43 | +VREF | Top node of internal reference ladder; sets +1 V offset for 0–2 V unipolar input range |
| 6, 40 | AIN | Analog input for ADC-A (pin 6) and ADC-B (pin 40); accepts 0–2 V with internal reference |
| 7, 39 | –VS | Negative supply (–5 V); substrate potential tied to –VS per die specification |
| 8, 38 | –VREF | Bottom node of internal reference ladder; establishes 0 V reference for unipolar mode |
| 9, 37 | +VS | Positive analog supply (5 V); powers comparator array and reference ladder |
| 10, 36 | ENCODE | TTL-compatible sample clock input; triggers conversion on rising edge for respective ADC |
| 11–17, 29–35 | D0–D7 | TTL digital outputs (LSB to MSB); latched, no pipeline delay; require 2 kΩ pull-downs above 40 MSPS |
| 12, 34 | COMP | Connection point for external 0.1 μF compensation capacitor to stabilize internal reference |
| 13, 33 | +VINT | Internal 2 V bandgap reference output; drives both +VREF ladders simultaneously |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9220ARZ | Single 10-bit, 10 MSPS ADC; no on-board reference; requires external REF and clock conditioning | Lacks dual-channel integration and I/Q timing coherence; suitable only for lower-speed, non-coherent dual-ADC implementations | Select when 10-bit resolution outweighs speed and channel matching requirements |
| ADS8364IPAG | 6-channel, 16-bit, 250 kSPS SAR ADC; serial LVDS interface; integrated reference; no interpolating architecture | Optimized for precision DC/low-frequency acquisition-not RF/IF sampling; incompatible timing model and bandwidth | Select for high-resolution sensor data logging, not communications or radar front ends |
Compared with AD9058AJD, AD9220ARZ trades off channel matching and speed for higher resolution at low sample rates, while ADS8364IPAG offers superior DC accuracy but lacks the 50 MSPS throughput and 175 MHz bandwidth needed for real-time RF digitization.

FAQ
What is the maximum guaranteed conversion rate for AD9058AJD?
The AD9058AJD is guaranteed to operate at 50 MSPS with full dynamic performance compliance-including SNR ≥45 dB and ENOB ≥7.2 bits at 10.3 MHz input. This rate is validated across the full 0°C to 70°C temperature range and requires 2 kΩ pull-down resistors on all D0–D7 outputs to ensure valid timing margins per the datasheet's Figure 4 timing diagram.
Does AD9058AJD include an internal voltage reference, and can it drive both ADCs?
Yes, AD9058AJD integrates a 2 V bandgap voltage reference (+VINT) explicitly designed to drive both internal reference ladders simultaneously. As confirmed in the "Using the AD9058" section (page 7), +VINT provides sufficient current and stability to support unipolar 0 V to 2 V operation for both ADC-A and ADC-B without external buffering or regulation.
What package type and lead count does AD9058AJD use?
AD9058AJD uses a hermetic 48-lead side-brazed ceramic dual in-line package (SBDIP), designated D-48 in the Ordering Guide. Its mechanical outline matches the D-48 footprint with 0.620 inch × 0.590 inch body size, 0.150 inch minimum height, and 0.023 inch lead thickness-verified in Rev. E, Page 10 of the official datasheet.
How is crosstalk rejection measured for AD9058AJD, and what is the specified value?
AD9058AJD crosstalk rejection is measured with full-scale 2.3 MHz and 3.5 MHz sine waves applied simultaneously to ADC-A and ADC-B, respectively, with synchronous 40 MSPS encoding. The undesired frequency's FFT amplitude relative to the desired tone yields 60 dBc typical rejection, as specified in the "Dynamic Performance" table on page 3 of the datasheet.
Is AD9058AJD still in active production, or is it obsolete?
AD9058AJD is marked "OBSOLETE" in the revision history and header of the provided datasheet (Rev. E, pages 2–11). While functional and supported for legacy systems, Analog Devices no longer manufactures or recommends it for new designs. Aetrix Electronics maintains limited legacy stock with full traceability for repair and sustainment programs.
