DAC8228FP

DAC8228FP Description

The DAC8228FP from Analog Devices Inc. is an 8-bit, dual-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in a 20-pin DIP (Through Hole) package, this IC operates with ±12V to ±15V dual power supplies for both analog and digital sections, ensuring robust performance in industrial environments. It features a parallel data interface for straightforward integration with microprocessors or logic circuits, delivering a settling time of 5µs for rapid signal updates. The DAC8228FP supports external voltage reference inputs, enabling flexible output range configuration. Though now obsolete, its legacy design remains relevant for systems requiring reliable, medium-resolution analog outputs.

DAC8228FP Features

• Dual 8-bit DACs: Two independent converters in a single package, reducing board space and cost.
• Fast Settling Time: 5µs ensures quick response in dynamic control systems.
• Wide Supply Range: ±12V to ±15V operation enhances compatibility with industrial power standards.
• Low INL/DNL: ±1 LSB (max) integral and differential nonlinearity for high accuracy.
• Parallel Interface: Simplifies direct connection to microcontrollers or digital logic.
• External Reference: Allows customization of output voltage ranges to suit application needs.
• Through-Hole Mounting: Robust 20-pin DIP package for easy prototyping and servicing.
