Product Introduction

Overview

The AD558KN/+, produced by Analog Devices Inc., is a complete voltage-output 8-bit digital-to-analog converter (DAC) integrated on a single monolithic chip. This device includes an output amplifier, a full microprocessor interface, and a precision voltage reference, eliminating the need for external components or trims to achieve full accuracy. The AD558KN/+ is designed using advanced monolithic bipolar technologies, including integrated injection logic (I²L) for the microprocessor interface and control logic, and a patented low-voltage bandgap circuit for the internal precision voltage reference. This design ensures reliable operation over a wide temperature range and supports various application environments.

Key Features

  • Complete DAC on a Single Chip: Includes output amplifier, full microprocessor interface, and precision voltage reference, eliminating the need for external components or trims.
  • Precision and Stability: Thin-film silicon-chromium resistors ensure stability and guaranteed monotonic operation over the entire operating temperature range. Laser-wafer-trimming of these resistors allows for absolute calibration at the factory to within ±1 LSB.
  • Wide Operating Voltage Range: Operates from a single positive power supply voltage between +4.5 V and +16.5 V, making it suitable for battery-operated, portable, automotive, or digital mainframe applications.
  • High Speed and Accuracy: Voltage settling to ±1/2 LSB for a full-scale step in 800 ns, ensuring high-speed and accurate conversions.
  • Military and Industrial Grades: Available in grades specified for use over different temperature ranges, including military grades screened to MIL-STD-883.

Applications

  • Digital Mainframe Systems: Suitable for high-performance digital systems requiring accurate and reliable analog output.
  • Automotive Systems: Operates over a wide voltage range, making it ideal for automotive applications where power supply variations are common.
  • Portable and Battery-Operated Devices: Efficient power consumption and wide operating voltage range make it suitable for battery-powered devices.
  • Military and Aerospace: Available in military grades and hermetically sealed packages, ensuring reliability in harsh environments.
  • Industrial Control Systems: Used in industrial control systems requiring precise analog outputs from digital inputs.
