**5962-8773802PA: Technical Specifications, Applications, and Sourcing Guide**
The **5962-8773802PA** is a highly reliable, military-grade integrated circuit (IC) that represents the pinnacle of performance for demanding applications. As a part number that falls under the strict **MIL-PRF-38535** certification, this device is manufactured to meet the stringent requirements of the Defense Supply Center (DSCC). This guide provides a detailed overview of its technical specifications, primary applications, and key considerations for sourcing this critical component.
**Technical Specifications**
The 5962-8773802PA is a radiation-hardened, high-performance **monolithic 12-Bit Digital-to-Analog Converter (DAC)**. Its design ensures exceptional accuracy and stability even in the most challenging environments. Key technical attributes include:
* **Resolution:** 12 Bits, ensuring fine analog output control.
* **Interface:** Parallel, for high-speed data transfer.
* **Supply Voltage:** Typically operates on ±15V and +5V power supplies.
* **Linearity:** Features excellent **Integral Non-Linearity (INL)** and **Differential Non-Linearity (DNL)**, which are critical for precision conversion accuracy.
* **Temperature Range:** Rated for operation over the full **military temperature range (-55°C to +125°C)**.
* **Qualification Level:** The "5962" prefix indicates it is a **QPL-listed (Qualified Parts List)** device, meaning it has undergone rigorous testing and qualification procedures mandated by the U.S. Department of Defense.
* **Packaging:** Available in a hermetically sealed ceramic package, offering superior protection against moisture, contaminants, and mechanical stress.
**Applications**
Due to its ruggedized design and high reliability, the 5962-8773802PA is not intended for commercial consumer electronics. Its primary applications are in fields where failure is not an option:
* **Aerospace and Defense Systems:** Used in **satellite communication systems**, flight avionics, radar systems, and missile guidance controls where radiation hardening is essential.
* **Critical Industrial Systems:** Employed in down-hole drilling equipment, nuclear power plant controls, and other high-reliability industrial environments that experience extreme temperatures and radiation.
* **Test and Measurement Equipment:** Found in high-precision calibration equipment and automated test systems (ATE) for military and aerospace hardware.
**Sourcing Guide**
Sourcing a component with a 5962 prefix requires careful consideration to avoid counterfeit parts and ensure performance.
* **Authorized Distributors:** The most reliable source is through **authorized distributors** or directly from the original manufacturer (e.g., Texas Instruments, which produces many such QML devices). They provide traceability and guarantees of authenticity.
* **Obsolete Components:** Many military-grade components have long production lifespans, but some may become obsolete. It is crucial to check the current **PCN (Product Change Notice)** and life-cycle status with the manufacturer.
* **Aftermarket & Brokers:** While aftermarket brokers can source hard-to-find parts, extreme vetting is necessary. Purchasers should insist on **certification paperwork**, **original lot codes**, and **hermeticity test reports** to verify authenticity.
* **Cost and Lead Time:** Be prepared for significantly higher costs and longer lead times compared to commercial-grade equivalents. This is a reflection of the extensive testing, materials, and manufacturing controls required.
**ICGOODFIND**
For engineers and procurement specialists, the 5962-8773802PA is an **ICGOODFIND** for mission-critical designs. Its DSCC qualification and radiation-hardened properties make it a benchmark for reliability in extreme environments, justifying the investment in rigorous sourcing practices.
