AD569KPZ

Overview

The AD569KPZ is a monolithic 16-bit digital-to-analog converter manufactured using Analog Devices' BiMOS II process. It features a single voltage output channel with a parallel interface and operates within a temperature range of -40°C to +85°C. The device is housed in a 28-lead plastic DIP package. Key electrical specifications include a typical nonlinearity of ±0.01% and a settling time of 3 microseconds to 16 bits. It utilizes external voltage references and supports both bipolar and unipolar output configurations.

Feature Summary

• Monolithic construction utilizing BiMOS II technology for high precision and low power consumption
• Guaranteed 16-bit monotonicity ensuring stable analog output transitions
• Integrated double-buffered input latches simplifying microprocessor interfacing
• Low drift and low noise characteristics suitable for high-resolution applications

Applications

• Robotics systems requiring precise motor control
• Closed-loop positioning mechanisms
• Microprocessor-based industrial process control
• High-resolution analog-to-digital converter front ends

Procurement Notes

Verify the specific suffix KPZ against official Analog Devices documentation to confirm pinout, temperature grade, and packaging details. Ensure compatibility with existing board layouts and thermal management requirements. Confirm RoHS compliance status through current manufacturer declarations before procurement.

Selection Notes

Select this component when 16-bit resolution and monotonic performance are critical for system accuracy. The parallel interface requires sufficient GPIO availability on the host controller. Consider the PDIP package constraints for automated assembly if surface mount alternatives are not feasible. Validate supply chain availability for the specific commercial grade variant.

Part Context

This part belongs to the AD569 family of 16-bit DACs from Analog Devices. The series is known for combining CMOS logic functions with bipolar linear circuitry on a single chip. This specific model represents the commercial temperature grade version in a standard plastic DIP package, distinct from military or ceramic variants.

Replacement Considerations

Direct replacements may include other AD569 family members with compatible pinouts but different suffixes indicating package or temperature variations. Verify that substitute parts maintain the same 16-bit resolution and parallel interface timing requirements.
