AD557JPZ

AD557JPZ Description

The AD557JPZ from Analog Devices Inc. is an 8-bit digital-to-analog converter (DAC) from the DACPORT® series, designed for precision voltage output applications. Housed in a 20-pin PLCC package, this surface-mount device integrates a parallel data interface and operates on a single 5V analog and digital supply, simplifying system design. With a settling time of just 1.5µs, it delivers rapid response for dynamic applications. The internal reference eliminates the need for external components, reducing board space and BOM complexity. Although marked Obsolete, it remains a reliable choice for legacy systems due to its ROHS3 compliance and REACH unaffected status.

AD557JPZ Features

• 8-bit resolution with voltage output for precise analog signal generation.
• Single 5V supply operation (analog and digital), minimizing power requirements.
• Parallel data interface for straightforward microcontroller interfacing.
• Internal reference ensures consistent performance without external circuitry.
• Fast 1.5µs settling time ideal for real-time control systems.
• Wide operating temperature range (0°C to 70°C) for industrial environments.
• Surface-mount PLCC package (20-pin) for compact PCB integration.
• RoHS3 compliant and REACH unaffected, adhering to environmental standards.
