AD7569JRZ-REEL

ADCs/DACs - Special Purpose Overview

The AD7569JRZ-REEL is an Analog Devices monolithic 8-bit analog I/O system in a 24-pin SOIC package. It integrates a high-speed successive approximation ADC with a 2 µs conversion time, a track/hold amplifier with 200 kHz bandwidth, an 8-bit DAC with output buffer, and an on-chip bandgap reference. The device supports single or dual 5 V supplies to enable unipolar (0 to +1.25 V/+2.5 V) or bipolar (±1.25 V/±2.5 V) ranges. Digital interfacing utilizes an 8-bit parallel port compatible with standard microprocessors.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-bit ADC with 2 µs conversion time and 200 kHz track/hold bandwidth
• Integrated 8-bit DAC with 1 µs settling time and buffered output
• On-chip temperature-compensated 1.25 V bandgap voltage reference
• Fast 8-bit parallel bus interface with timing compatible with modern microprocessors

ADCs/DACs - Special Purpose Applications

• Microprocessor-based data acquisition systems
• Industrial process control loops
• Signal conditioning interfaces for embedded controllers

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'JRZ-REEL' against the manufacturer's current ordering guide to confirm the SOIC-24 package and reel packaging configuration. Ensure the J-grade commercial temperature range (0°C to +70°C) aligns with the application requirements. Cross-reference the datasheet revision B specifications for absolute maximum ratings and power dissipation limits before finalizing procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a complete 8-bit analog I/O solution is required without external components. The AD7569 provides a single DAC output, whereas the AD7669 variant offers dual DACs. Designers must account for the ±2 LSB total unadjusted error and ensure supply voltages remain within the 4.75 V to 5.25 V range for specified performance. Verify logic level compatibility for the 8-bit parallel interface.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7569/AD7669 family of complete analog I/O systems fabricated using Linear-Compatible CMOS (LC2MOS) technology. The AD7569 variant specifically contains one DAC channel, distinguishing it from the dual-channel AD7669. The 'JRZ' designation indicates the commercial temperature grade and SOIC-24 package, while '-REEL' specifies tape-and-reel delivery.
