AD390JD

AD390JD Description

The AD390JD from Analog Devices Inc. is a high-precision 12-bit quad digital-to-analog converter (DAC) designed for demanding industrial and instrumentation applications. Housed in a 28-pin CDIP (Ceramic Dual In-Line Package), this through-hole-mount DAC offers robust performance with ±0.25 LSB INL (Integral Non-Linearity) and ±0.5 LSB DNL (Differential Non-Linearity), ensuring accurate analog output. It operates over a 0°C to 70°C temperature range and supports both external and internal voltage references, providing flexibility in system design. The parallel data interface simplifies integration with microprocessors, while the ±13.5V to 16.5V dual analog supply enables wide output voltage swings.

AD390JD Features

• Quad 12-bit DACs: Four independent converters in a single package, reducing board space and cost.
• Fast Settling Time: 8µs settling time for rapid response in dynamic applications.
• High Accuracy: Tight INL/DNL specifications ensure precision in control systems.
• Flexible Reference Options: Supports internal or external references for design adaptability.
• Robust Packaging: 28-CDIP ceramic package ensures reliability in harsh environments.
• Wide Supply Range: ±13.5V to 16.5V analog supply accommodates diverse system requirements.

AD390JD Applications

• Industrial Automation: Ideal for process control, PLCs, and motor control due to its high accuracy and multi-channel capability.
