Product details
Overview
AD572SD/883B from Analog Devices is an obsolete 12-bit monolithic D/A converter with ±1/2 LSB integral nonlinearity, ±1/2 LSB differential nonlinearity, and 0.05% full-scale accuracy, used in precision military instrumentation and test equipment requiring MIL-STD-883 compliance.
For engineers reviewing the AD572SD/883B datasheet, AD572SD/883B pinout, AD572SD/883B application, or AD572SD/883B equivalent, key selection considerations include its hermetically sealed ceramic DIP-18 package, dual-supply operation (±15 V), unbuffered current output, and qualification per MIL-STD-883 Class B.
Technical Context
The AD572SD/883B implements a segmented R-2R ladder architecture with laser-trimmed thin-film resistors to achieve monotonic 12-bit performance across temperature. It requires external op-amp for voltage output conversion and operates with TTL/CMOS-compatible digital inputs.
Its internal reference is omitted - users must supply an external precision reference (e.g., AD587) to set full-scale output. The device supports both unipolar and bipolar output configurations via external component selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - delivers 4096 discrete output levels for high-precision analog control |
| INL | ±1/2 LSB - ensures accurate transfer function without calibration in closed-loop systems |
| DNL | ±1/2 LSB - guarantees monotonicity critical for servo and feedback applications |
| Full-Scale Accuracy | ±0.05% - enables direct use in calibrated test instrumentation without trimming |
| Supply Voltage | ±15 V - mandates dual-rail power design with low-noise linear regulation |
| Output Type | Unbuffered current - requires external op-amp (e.g., OP177) for stable voltage conversion |
Pinout & Package
AD572SD/883B is housed in a hermetically sealed 18-pin ceramic dual-in-line package (DIP-18) with metal lid, qualified to MIL-STD-883 Class B for extended temperature operation (–55°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Data Inputs (D0–D7) | LSB-first parallel TTL/CMOS inputs; require proper termination to avoid noise-induced glitches |
| 9, 10, 11, 12, 13, 14 | Data Inputs (D8–D11) | MSB-first inputs; all 12 bits must be latched simultaneously for monotonic step response |
| 15 | Reference Input | Accepts external precision voltage reference (e.g., 10 V); sets full-scale current output |
| 16 | IOUT | Unbuffered current output; requires virtual-ground op-amp configuration for voltage conversion |
| 17 | VEE | Negative supply (–15 V); must be decoupled locally with 0.1 µF ceramic + 10 µF tantalum |
| 18 | VCC | Positive supply (+15 V); same decoupling requirement as VEE |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±1/2 LSB INL/DNL without system-level calibration |
| MIL-STD-883 Class B screening | Validates reliability for aerospace and defense platforms operating at –55°C to +125°C |
| Monolithic R-2R ladder architecture | Eliminates hybrid assembly risks and improves long-term gain stability vs. modular DACs |
| TTL/CMOS-compatible inputs | Direct interface with 80C85, 8085A, or 68000-based controller buses without level-shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD572SE/883B | Same die, plastic DIP-18 package; not hermetically sealed or MIL-STD-883 Class B screened | Suitable only for lab-grade or non-mission-critical environments below +85°C | Select AD572SE/883B only if environmental ruggedness and extended temperature range are not required. |
| AD7528KPZ | 8-bit dual DAC, no MIL qualification, different pinout, requires external reference and op-amp | Used in industrial PLC I/O modules where 12-bit resolution is unnecessary | Choose AD7528KPZ only when lower resolution and commercial-grade reliability suffice. |
Compared with AD572SE/883B and AD7528KPZ, the AD572SD/883B uniquely provides 12-bit monotonicity with hermetic sealing and full MIL-STD-883 Class B qualification - essential for flight-critical and strategic systems where parameter drift under stress cannot be tolerated.

FAQ
Is AD572SD/883B still in production?
No, AD572SD/883B is officially obsolete per Analog Devices' product discontinuance notice. However, Aetrix Electronics maintains legacy inventory with full traceability and offers controlled distribution for ongoing maintenance and repair of certified military platforms where redesign is not authorized.
What is the maximum operating temperature for AD572SD/883B?
The AD572SD/883B is rated for operation from –55°C to +125°C, verified per MIL-STD-883 Method 1010.8 temperature cycling and Method 2002.4 steady-state life testing. This range applies only to units bearing the /883B suffix and packaged in hermetic ceramic DIP-18.
Does AD572SD/883B include an internal voltage reference?
No, AD572SD/883B does not include an internal voltage reference. It requires an external precision reference - typically the AD587 or LM399 - connected to Pin 15 to establish full-scale output current. Reference stability directly determines DAC accuracy over time and temperature.
Can AD572SD/883B be used with single-supply systems?
No, AD572SD/883B requires dual ±15 V supplies (Pins 17 and 18) for proper operation. Its internal circuitry is not designed for single-rail biasing, and attempting single-supply use will result in undefined output behavior and potential damage.
What op-amp is recommended for voltage output conversion with AD572SD/883B?
The OP177 is the op-amp explicitly recommended in the AD572SD/883B datasheet for I-to-V conversion due to its low offset voltage (25 µV max), low drift (0.1 µV/°C), and ability to maintain stability with the DAC's capacitive load. Other options include AD707 and LT1012 when OP177 is unavailable.
