AD7569JPZ-REEL

ADCs/DACs - Special Purpose Overview

The AD7569JPZ-REEL is an 8-bit analog I/O system fabricated in LC2MOS technology, integrating a successive approximation ADC, a track/hold circuit, and a DAC with an output buffer amplifier. It features a single-channel ADC with a 2 μs conversion time and a sampling rate up to 400 kS/s. The device includes an on-chip bandgap reference and supports unipolar (0 to +1.25 V or 0 to +2.5 V) or bipolar (±1.25 V or ±2.5 V) ranges via the RANGE pin. It operates on a single +5 V supply or dual ±5 V supplies, utilizing a parallel 8-bit interface compatible with TTL and CMOS logic levels.

• Single-channel DAC with output buffer amplifier and 1 μs typical settling time
• On-chip temperature-compensated 1.25 V bandgap voltage reference
• Fast parallel bus interface with microprocessor control lines (CS, WR, RD, ST)

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 that the 'JPZ' suffix corresponds to the PLCC package variant as defined in the manufacturer's ordering guide. Confirm the specific grade (J version) matches the required commercial operating temperature range of 0°C to +70°C. Ensure the REEL packaging designation aligns with automated assembly requirements.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a complete, monolithic 8-bit A/D and D/A solution is required without external components. Choose the J version for commercial temperature applications. Verify that the 8-bit resolution and 400 kS/s maximum sampling rate meet system throughput needs. Ensure the parallel interface timing constraints are compatible with the target microprocessor.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7569/AD7669 family of complete analog I/O systems. The AD7569 variant provides a single DAC output, whereas the AD7669 offers dual DAC outputs. Both share identical ADC specifications and internal architecture, differing primarily in the number of digital-to-analog channels available on the chip.
