AD7628KR

AD7628KR Description

The AD7628KR from Analog Devices Inc. is an 8-bit, dual-channel digital-to-analog converter (DAC) designed for precision analog output applications. Housed in a 20-pin SOIC package, this surface-mount IC operates with dual power supplies (10.8V to 15.75V for both analog and digital domains), ensuring robust performance in industrial and instrumentation systems. It features a parallel data interface for high-speed communication and supports an external reference voltage for flexible system integration. With a fast settling time of 400ns and low integral/differential non-linearity (±0.5 LSB INL, ±1 LSB DNL max), the AD7628KR delivers accurate and stable analog outputs.

AD7628KR Features

• Dual 8-bit DACs: Two independent channels for multi-output systems.
• Wide Supply Range: Supports 10.8V to 15.75V for analog and digital operation.
• Fast Settling Time: 400ns ensures rapid response in dynamic applications.
• Low Nonlinearity: ±0.5 LSB INL and ±1 LSB DNL for high precision.
• Parallel Interface: Enables straightforward integration with microcontrollers and FPGAs.
• External Reference: Allows customization of output range.
• Industrial-Grade Reliability: MSL 1 (Unlimited) moisture sensitivity for robust handling.

AD7628KR Applications

The AD7628KR excels in systems requiring high-speed, multi-channel analog outputs, such as:

• Industrial Automation: Control signal generation for PLCs and motor drives.
• Test & Measurement Equipment: Precision waveform generation and calibration.
• Medical Instrumentation: Analog control in diagnostic devices.
• Defense/Aerospace: Ruggedized systems needing stable DAC performance.
• Audio Processing: Multi-channel signal routing in professional audio gear.

Conclusion of AD7628KR

The AD7628KR is a discontinued but historically reliable DAC solution, offering dual-channel 8-bit resolution, fast settling, and low nonlinearity for demanding analog output tasks. While newer models may offer higher resolution or integrated features, its robust design and parallel interface make it a proven choice for legacy systems or applications prioritizing simplicity and speed. Engineers seeking a cost-effective, industrial-grade DAC for multi-output designs may still find value in existing stock or alternative ADI offerings.
