Analog Devices AD669SQ/883B Precision DAC

The AD669SQ/883B from Analog Devices Inc. stands as a testament to precision and reliability in the realm of digital-to-analog converters (DACs). This high-performance monolithic 16-bit DAC is designed to deliver exceptional accuracy and stability, making it an ideal choice for applications that demand the highest level of precision, such as military, aerospace, and high-end industrial equipment.

Constructed with Analog Devices' advanced thin-film resistor technology, the AD669SQ/883B ensures a low noise output and a stable full-scale voltage. This technology also contributes to the DAC's impressive temperature performance, boasting a temperature coefficient of just 5 ppm/°C, which guarantees consistent performance even under varying environmental conditions.

One of the key features of the AD669SQ/883B is its versatile reference input range. This allows the device to accommodate a variety of reference voltages, thereby providing flexibility in system design. Additionally, the DAC features a fast settling time of 4µs to 0.01%, which is critical for applications that require rapid changes in output levels without sacrificing accuracy.

The AD669SQ/883B operates on a ±12V to ±15V power supply, ensuring compatibility with a wide range of existing systems. It also includes a double-buffered interface, which enhances the ease of interfacing with microprocessors and digital systems. The on-chip output amplifier can swing to both supply rails, providing a full-scale output voltage range for maximum dynamic range.

Encased in a hermetically sealed 24-lead CERDIP package, the AD669SQ/883B is built to withstand harsh environments and meet stringent military standards for quality and reliability, denoted by its 883B grade. This level of packaging ensures that the device is not only robust but also protected against environmental factors that could otherwise compromise its performance.

In summary, the AD669SQ/883B is a superior choice for designers who require a high-precision DAC that can deliver consistent and reliable performance across a broad range of applications. Its combination of advanced technology, flexibility, and robust design makes it a standout product in Analog Devices' extensive portfolio of precision DACs.
