Product Details
AD390TD/883B - ADI High-Precision Quad 12-Bit CMOS DAC (MIL-STD-883 Compliant)
The AD390TD/883B is a monolithic, high-performance Quad 12-bit Digital-to-Analog Converter (DAC) manufactured by Analog Devices. Fully qualified to MIL-STD-883B standards, it provides four independent, high-speed DACs in a single 28-pin ceramic package. With its microprocessor-compatible interface and exceptional accuracy over the full military temperature range, it is an essential component for aerospace, defense, and high-precision instrumentation.
Mission Critical: Engineered for extreme environments, the "TD" grade ensures consistent 12-bit monotonicity and precision from -55°C to +125°C.
Overview & Architectural Excellence
The AD390TD/883B is designed for applications where PCB real estate is at a premium and system reliability cannot be compromised. By integrating four 12-bit DACs, double-buffered data latches, and a control logic stage into a 28-pin Side-Brazed Ceramic DIP, it drastically reduces the component count and complexity of multi-channel analog output systems.
This device features a sophisticated Microprocessor-Compatible Interface, allowing it to be easily interfaced with 8-bit or 16-bit bus systems. The DACs are laser-trimmed at the wafer level to ensure tight linearity specifications and minimal gain drift, making it ideal for high-resolution control systems and automated test equipment (ATE).
About Analog Devices (ADI)
Analog Devices, Inc. (ADI) is a world leader in the design, manufacture, and marketing of a broad portfolio of high-performance analog, mixed-signal, and digital signal processing (DSP) integrated circuits (ICs).
ADI's products play a fundamental role in converting, conditioning, and processing real-world phenomena such as light, sound, temperature, motion, and pressure into electrical signals. For decades, ADI has been the gold standard for high-reliability components used in space, defense, and healthcare industries.
Key Advantages
Significant space savings on high-density military-grade PCBs compared to using discrete DACs.
Guaranteed performance from -55°C to +125°C with 12-bit accuracy maintained throughout.
Integrated CMOS technology ensures high performance with minimal thermal dissipation.
Allows simultaneous updating of all four DAC outputs to eliminate time-skew in multi-channel systems.
Package & Mechanical Details
The AD390TD/883B is housed in a high-reliability 28-Pin Ceramic Side-Brazed DIP (DH-28). This hermetic package is designed to withstand extreme thermal cycling and mechanical vibration.
- Package Material: Alumina Ceramic with Hermetic Seal.
- Lead Finish: Gold or Solder dipped (per MIL-Spec).
- Mounting Type: Through-hole or Socket.
- Reliability: Tested for salt spray, moisture, and fine-leak detection.
Pin Functions & Terminal Map
The AD390 terminal layout supports an 8-bit or 12-bit data bus through its control logic pins.
