AD561KNZ

Overview

The AD561KNZ is a monolithic 10-bit digital-to-analog converter manufactured by Analog Devices. It utilizes an R-2R resistor ladder architecture to convert parallel digital inputs into analog signals. The device supports both bipolar and unipolar output configurations, offering flexibility for various signal conditioning needs. It operates within a supply voltage range of 4.5 V to 16.5 V and features a maximum settling time of 250 ns. The component is housed in a 16-pin PDIP package designed for through-hole mounting.

Feature Summary

• Integrates an R-2R resistor ladder network for precise digital-to-analog conversion
• Supports flexible bipolar and unipolar output polarity configurations
• Features a parallel data interface for direct connection to microprocessors
• Provides external voltage reference input capability for improved accuracy

Applications

• Audio signal processing systems requiring high-resolution digital control
• Industrial process control loops utilizing parallel digital interfaces
• Test and measurement equipment needing stable analog voltage generation

Procurement Notes

Verify the specific suffix KNZ against official Analog Devices documentation to confirm the PDIP-16 package and commercial temperature grade. Ensure compatibility with existing PCB footprints for through-hole assembly. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement orders.

Selection Notes

Select this component when a 10-bit resolution and parallel interface are required for single-channel applications. Consider the 250 ns settling time for bandwidth limitations in your system design. Verify that the external reference voltage requirements align with the available power supply rails for optimal performance.

Part Context

This part belongs to the AD561 series of monolithic DACs from Analog Devices. The series is characterized by its use of R-2R ladder technology and availability in multiple package styles including ceramic DIP and plastic DIP variants. It serves as a foundational component for older parallel-based digital control architectures.

Replacement Considerations

Direct replacements include other AD561 variants such as AD561JCHIPS or AD561TD/883B, provided the package type matches the board layout. Verify electrical specifications and pinouts carefully when substituting between different package formats within the same family.
