AD390KD

AD390KD Description

The AD390KD is a 12-bit quad digital-to-analog converter (DAC) from Analog Devices Inc., designed for precision voltage output applications. Housed in a 28-pin CDIP package, this through-hole-mount DAC offers four independent D/A converters with a parallel data interface, making it suitable for systems requiring multiple analog outputs. The device operates over a ±13.5V to 16.5V analog supply range and features a ±0.25 LSB INL and ±0.5 LSB DNL, ensuring high linearity and accuracy. With an 8µs settling time, it delivers fast response for dynamic control systems. Though now obsolete, it remains a robust choice for legacy designs due to its ROHS3 compliance and REACH unaffected status.

AD390KD Features

• 12-bit resolution with four independent DACs for multi-channel applications.
• Low INL/DNL errors (±0.25 LSB INL, ±0.5 LSB DNL) for high precision.
• Parallel data interface for straightforward integration with microprocessors.
• Flexible reference options: supports external or internal references.
• Wide analog supply range (±13.5V to 16.5V) for versatile system compatibility.
• Fast settling time (8µs) for rapid signal updates.
• Through-hole mounting (28-CDIP) for reliable mechanical stability.
• Industrial temperature range (0°C to 70°C) for stable operation in harsh environments.

AD390KD Applications

The AD390KD is ideal for applications requiring high-precision analog outputs with multi-channel capability, such as:

• Industrial automation: Control systems for PLCs and motor drives.
