Overview
The AD660SQ/883B is a military-grade, monolithic 16-bit digital-to-analog converter (DAC) from the DACPORT family. Manufactured using BiMOS II technology, it integrates a laser-trimmed buried Zener voltage reference, double-buffered latches, and an output amplifier on a single chip. The device supports serial or byte input interfaces with pin-selectable MSB/LSB first ordering and facilitates daisy-chaining via a serial output pin. It offers unipolar (0 V to 10 V) or bipolar (−10 V to +10 V) output ranges without external components. Key electrical specifications include ±1 LSB integral nonlinearity, 15-bit monotonicity over temperature, and a typical glitch impulse of 15 nV-s.
Feature Summary
- Military-compliant MIL-STD-883 specification with extended temperature range of −55°C to +125°C
- Integrated 10.000 V buried Zener reference with ±0.1% maximum error and ±15 ppm/°C drift
- Double-buffered latch architecture enabling simultaneous multi-DAC updates and elimination of data skew
- Flexible digital interface supporting serial (SPI/MICROWIRE compatible) and byte-load modes
Applications
- High-reliability aerospace and defense instrumentation systems
- Precision test and measurement equipment requiring stable DC references
- Industrial control loops demanding high linearity and low noise
- Medical imaging devices requiring precise analog signal generation
Procurement Notes
Verify that the component lot carries the specific MIL-STD-883 compliance marking required for the application. Confirm the package type is the 24-lead 300 mil CERDIP variant associated with the SQ grade. Ensure supply chain documentation meets defense industry traceability standards prior to procurement.
Selection Notes
Select the AD660SQ/883B when operation in extreme environments between −55°C and +125°C is mandatory. This grade provides stricter testing conditions compared to commercial AN/BN or industrial AR/BR variants. Use this part if the internal 10 V reference stability and military reliability ratings are critical design constraints.
Part Context
The AD660 series utilizes Analog Devices' BiMOS II process to combine high-precision bipolar linear circuits with low-power CMOS logic. The SQ grade specifically denotes the ceramic DIP packaging and military qualification. This architecture ensures long-term stability and 15-bit monotonicity independent of time and temperature variations.
Replacement Considerations
Commercial equivalents such as the AD660AN, AD660BN, AD660AR, or AD660BR lack the MIL-STD-883 certification and have a reduced operating temperature range of −40°C to +85°C. Substitution requires verification that the environmental and reliability requirements can be met by the lower-grade parts.
