AD7569JP-REEL

ADCs/DACs - Special Purpose Overview

The AD7569JP-REEL is an LC2MOS complete, 8-bit analog I/O system manufactured by Analog Devices Inc. It integrates a successive approximation register (SAR) analog-to-digital converter and an 8-bit digital-to-analog converter on a single monolithic chip. The device operates with a single +5V supply and features parallel CMOS/TTL-compatible outputs. Key electrical specifications include a sampling rate of 500 kS/s, a signal-to-noise ratio of 46 dB, and a power dissipation of 85 mW. It utilizes an internal reference voltage and exhibits a gain error of +/- 2 LSB with an integral nonlinearity of +/- 0.5 LSB.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-bit ADC and DAC in a single LC2MOS monolithic chip
• High-speed data acquisition with a 500 kS/s sampling rate
• Internal reference voltage eliminates external components
• Parallel interface with CMOS/TTL compatible logic levels

ADCs/DACs - Special Purpose Applications

• Data acquisition systems requiring integrated analog input and output
• Industrial process control loops
• Portable instrumentation with single-supply requirements

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'JP-REEL' against current manufacturer documentation to confirm package type and reel packaging status. Availability may be limited as this part number appears discontinued or restricted in major distributor inventories. Ensure compatibility with existing PCB footprints for the specified package style before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when an 8-bit resolution with high-speed conversion is required in a single-chip solution. The internal reference simplifies board design compared to external reference variants. Verify that the parallel interface timing meets system requirements and that the operating temperature range aligns with the application environment.

ADCs/DACs - Special Purpose Part Context

The AD7569 belongs to the AD7569/AD7669 family of complete analog I/O systems. The 'JP' designation typically indicates a plastic DIP package, while '-REEL' specifies tape-and-reel packaging for automated assembly. This series was designed to reduce component count in data acquisition applications by combining ADC, DAC, and clock functions.

ADCs/DACs - Special Purpose Replacement Considerations

Check for direct pin-compatible replacements within the AD7569 family, such as AD7569KNZ or AD7569BRZ, noting differences in package (PDIP vs SOIC) and temperature rating. Verify if newer generations from Analog Devices offer improved linearity or speed while maintaining functional compatibility.
