AD7569JPZ

ADCs/DACs - Special Purpose Overview

The AD7569JPZ is an 8-bit analog I/O system fabricated in LC2MOS technology, integrating a successive approximation ADC with a 2 μs conversion time and a DAC with a 1 μs settling time. It features an on-chip track/hold amplifier with 200 kHz bandwidth and a temperature-compensated 1.25 V bandgap reference. The device supports single or dual 5 V supplies, enabling unipolar (0 to +1.25 V/+2.5 V) or bipolar (±1.25 V/±2.5 V) ranges via the RANGE pin. Digital interfacing utilizes an 8-bit parallel port compatible with standard microprocessor control lines.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-bit SAR ADC with 2 μs conversion time and 200 kHz bandwidth track/hold
• DAC with output buffer amplifier achieving 1 μs typical settling time
• On-chip 1.25 V bandgap voltage reference for precision ADC and DAC operation
• Fast parallel bus interface with access times under 75 ns

ADCs/DACs - Special Purpose Applications

• Microprocessor-based data acquisition systems
• Industrial process control loops
• Instrumentation requiring integrated analog I/O

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix JPZ against the manufacturer's current ordering guide to confirm package type and temperature range availability. Ensure that the required operating temperature range matches the J version specifications (0°C to +70°C). Confirm RoHS compliance status through official documentation prior to procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the AD7569JPZ when a single-channel DAC is required; the AD7669 variant provides dual DAC outputs. Choose this component if the application demands a complete analog I/O solution without external trimming. Verify that the 8-bit resolution and 200 kHz sampling rate meet the system's dynamic performance requirements.

ADCs/DACs - Special Purpose Part Context

The AD7569JPZ belongs to the AD7569/AD7669 family of complete analog I/O systems. This series combines ADC and DAC functions on a single monolithic chip using Linear-Compatible CMOS (LC2MOS) technology. The 'J' designation indicates a commercial temperature range, while 'P' denotes the plastic leaded chip carrier package option.
