Product details
Overview
AD9012TQ/883B from Analog Devices is a military-grade 8-bit, 100 MSPS TTL-compatible analog-to-digital converter fabricated in advanced bipolar process. It delivers 0.5 LSB integral linearity, 160 MHz large-signal analog input bandwidth, and 7.5 effective bits at 1.23 MHz - enabling high-fidelity digitization of radar pulses and RF IF signals without external track-and-hold. Used in electronic warfare receivers and digital oscilloscopes requiring MIL-STD-883 Class B compliance.
For engineers reviewing the AD9012TQ/883B datasheet, AD9012TQ/883B pinout, AD9012TQ/883B application, or AD9012TQ/883B equivalent, key selection considerations include its –55°C to +125°C operating range, ceramic DIP (Q-28) package, dual ±5.2 V/±5.0 V supply architecture, overflow handling via OVERFLOW INH pin, and 16 pF analog input capacitance for wideband amplifier interfacing.
Technical Context
The AD9012TQ/883B implements a flash ADC architecture with 256 parallel comparators and TTL-output latches triggered on the rising edge of ENCODE. Its analog front-end uses a precision resistor ladder (40–110 Ω) referenced to +VREF, –VREF, and REFMID, supporting differential reference voltage of 2.0 V.
Timing behavior includes 3.8 ns aperture delay, 15 ps aperture jitter, and 4–11 ns output propagation delay (tPD), with all digital outputs synchronized to the ENCODE clock edge. The HYSTERESIS pin allows 0–10 mV programmable comparator hysteresis to improve noise immunity in harsh EMI environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - defines quantization step size and dynamic range for digitizing analog waveforms. |
| Max Conversion Rate | 100 MSPS - supports real-time sampling of signals up to 50 MHz Nyquist bandwidth. |
| Analog Input Bandwidth | 160 MHz - enables accurate acquisition of fast-rising pulses (e.g., radar returns) without external track-and-hold. |
| Differential Linearity | 0.5 LSB (typ) - ensures monotonicity and minimizes code missing or differential gain error in linear systems. |
| Input Capacitance | 16 pF - low loading permits direct interface with wideband amplifiers like AD9610 without bandwidth degradation. |
| Power Dissipation | 955 mW - requires thermal management in sealed military enclosures; junction temp must stay ≤150°C. |
| Aperture Uncertainty | 15 ps - limits SNR degradation at high input frequencies; critical for coherent signal processing. |
Pinout & Package
AD9012TQ/883B is housed in a 28-lead ceramic dual-in-line package (CERDIP, Q-28), compliant with MIL-STD-883 Class B, rated for –55°C to +125°C operation. Package dimensions: 0.610" × 0.500" × 0.225" (15.49 mm × 12.70 mm × 5.72 mm), with 0.100" lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 4–9, 21–23, 28 | DIGITAL –VS / ANALOG –VS / DIGITAL GROUND / ANALOG GROUND | Separate analog/digital ground and negative supply pins minimize coupling between sensitive analog paths and noisy digital switching. |
| 11, 13, 18 | DIGITAL +VS | Three dedicated +5.0 V digital supply pins reduce IR drop and ensure stable TTL output drive across all 8 data bits and overflow. |
| 10, 15 | ANALOG INPUT | Differential input pair - must be driven symmetrically with equal-length traces to avoid aperture delay skew. |
| 14, 11 | +VREF, –VREF | Reference ladder endpoints - require low-impedance, low-noise sourcing; +VREF typically tied to analog ground. |
| 12 | OVERFLOW INH | Active-low control: floating (–5.2 V) enables return-to-zero overflow coding; grounded enables non-return-to-zero mode. |
| 3 | HYSTERESIS | Voltage-controlled hysteresis (0–10 mV) improves noise margin in high-EMI ECM/ECCM platforms. |
| 17 | ENCODE | TTL-compatible rising-edge-triggered sampling command - rise/fall times <30 ns required for full 100 MSPS operation. |
| 15–16, 19, 24–26 | D1 (LSB) to D8 (MSB) | TTL-level parallel digital outputs - latched on ENCODE edge; D1–D8 represent unsigned binary word (0–255). |
| 27 | OVERFLOW | Separate TTL output indicating AIN ≥ +VREF - used for automatic gain control or clipping detection in radar warning receivers. |
Key Features
| Feature | Design Value |
|---|---|
| 100 MSPS encode rate | Enables real-time digitization of L/S-band RF IF signals and ultrafast transient pulses in EW systems. |
| 16 pF analog input capacitance | Reduces need for buffer amplifiers and preserves bandwidth when driving from hybrid amplifiers (e.g., AD9610). |
| MIL-STD-883 Class B compliance | Validated for extended temperature cycling, hermeticity, and radiation hardness - suitable for aerospace and defense deployments. |
| Overflow inhibit logic | Configurable overrange response (return-to-zero vs. non-return-to-zero) simplifies downstream data processing in pulse analysis firmware. |
| 15 ps aperture jitter | Supports >7.5 ENOB at 10 MHz input frequency - essential for high-fidelity signal intelligence (SIGINT) applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9012SQ/883B | Same Q-28 CERDIP package and MIL-STD-883B compliance, but specified for 0.75 LSB linearity (vs. 0.5 LSB for AD9012TQ/883B). | Suitable where tighter linearity is not required - e.g., coarse pulse amplitude estimation in early-warning receivers. | Select AD9012SQ/883B only if system-level linearity budget allows 0.25 LSB relaxation; otherwise AD9012TQ/883B is preferred for precision SIGINT. |
| AD9042BRS | 10-bit, 41 MSPS BiCMOS ADC in 28-lead SSOP; lower speed but higher resolution and integrated reference; not MIL-qualified. | Used in commercial ATE and communications test gear where radiation tolerance and extended temperature are not required. | AD9042BRS offers higher resolution but cannot replace AD9012TQ/883B in military platforms due to lack of MIL-STD-883 qualification and lower sample rate. |
Compared with AD9012SQ/883B, AD9012TQ/883B provides superior linearity for precision amplitude measurement; compared with AD9042BRS, it trades resolution for speed and ruggedness - making it irreplaceable in hardened radar warning and ECM hardware where 100 MSPS and –55°C to +125°C operation are mandatory.

FAQ
What is the operating temperature range of the AD9012TQ/883B?
The AD9012TQ/883B is rated for –55°C to +125°C operation and qualified per MIL-STD-883 Class B. This extended range is achieved using a ceramic DIP (Q-28) package and internal design optimizations for thermal stability across military platform environments - including avionics bays and ground vehicle electronics compartments.
Does the AD9012TQ/883B require an external track-and-hold amplifier?
No, the AD9012TQ/883B does not require an external track-and-hold amplifier due to its 160 MHz large-signal analog input bandwidth and low 16 pF input capacitance. This allows direct digitization of fast-rising radar pulses and IF signals while maintaining 8-bit accuracy - a key advantage over slower ADCs in real-time EW and guidance systems.
How is overflow handled in the AD9012TQ/883B?
The AD9012TQ/883B uses the OVERFLOW INH pin to configure overflow behavior: when floating at –5.2 V (enabled), OVERFLOW goes HIGH and all data outputs go LOW for overrange inputs (return-to-zero); when grounded (inhibited), OVERFLOW goes LOW and all data outputs go HIGH (non-return-to-zero). This dual-mode capability is implemented directly in the AD9012TQ/883B's internal decoding logic.
What power supplies does the AD9012TQ/883B require?
The AD9012TQ/883B requires three distinct supply rails: +5.0 V for digital circuitry (pins 11, 13, 18), –5.2 V for analog and digital circuitry (pins 14, 21, 22, 28), and analog ground (pins 16, 19). Total nominal power dissipation is 955 mW, with +5.0 V supply drawing ~45 mA and –5.2 V supply drawing ~179 mA at 25°C.
Is the AD9012TQ/883B pin-compatible with other AD9012 variants?
Yes, all AD9012 variants - including AD9012TQ/883B, AD9012SQ/883B, AD9012TE/883B, and AD9012SE/883B - share identical pinouts and package footprints (Q-28 CERDIP or E-28A LCC). This allows direct substitution within the same package type, provided the linearity (0.5 LSB vs. 0.75 LSB) and temperature grade meet system requirements.
