AD7569JP

ADCs/DACs - Special Purpose Overview

The AD7569JP is an 8-bit analog I/O system on a single monolithic chip, fabricated in LC2MOS technology. It integrates a successive approximation ADC with a 2 μs conversion time and track/hold, alongside a DAC with a 1 μs settling time output buffer. The device features an internal bandgap reference and supports single or dual 5 V supplies. Digital interfacing utilizes an 8-bit parallel I/O port compatible with standard microprocessor control lines. The JP suffix indicates a 28-pin Plastic Leaded Chip Carrier (PLCC) package with a commercial temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Feature Summary

• Complete 8-bit Analog I/O System: Integrates SAR ADC, Track/Hold, DAC, and Output Amplifier on one chip.
• Internal Bandgap Reference: Provides precision voltage for both ADC and DAC without external components.
• Fast Bus Interface: Compatible with modern microprocessors, featuring bus access times under 75 ns.
• Flexible Supply Options: Operates on single +5 V or dual ±5 V supplies for unipolar or bipolar ranges.

ADCs/DACs - Special Purpose Applications

• Microprocessor-based data acquisition systems requiring integrated analog interfaces.
• Industrial process control applications needing precise analog input/output handling.
• Test and measurement equipment utilizing fast sampling and conversion capabilities.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix JP corresponds to the 28-pin PLCC package configuration. Confirm that the commercial temperature grade (0°C to +70°C) meets the operational requirements of the target environment. Ensure compatibility with existing PCB footprints for the PLCC form factor during procurement planning.

ADCs/DACs - Special Purpose Selection Notes

Select the AD7569JP when a 28-pin PLCC package is required for the design. Choose this variant over DIP or SOIC options if surface-mount assembly with a larger footprint is preferred. Verify that the commercial temperature range is sufficient; otherwise, consider industrial or extended temperature grades available in other packages.

ADCs/DACs - Special Purpose Part Context

The AD7569JP belongs to the AD7569/AD7669 family of complete 8-bit analog I/O systems. While the AD7569 provides a single DAC output, the AD7669 variant offers dual DAC outputs. The JP designation specifically identifies the plastic leaded chip carrier package option within the broader product line manufactured by Analog Devices.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements include other AD7569 variants such as AD7569JN (DIP) or AD7569JR (SOIC), provided the package change is acceptable. For dual-channel requirements, the AD7669 series may be considered, though pin configurations differ slightly between single and dual DAC versions.
