Specialized datasheet and documents for AD7669JN

AD7669JN

Specialized Overview

The AD7669JN is an 8-bit analog I/O system on a single monolithic chip, featuring a successive approximation ADC with 2 μs conversion time and two DACs with output buffer amplifiers. It operates on single or dual 5 V supplies, supporting unipolar (0 to +1.25/2.5 V) and bipolar (±1.25/±2.5 V) ranges via the RANGE pin. The device includes an on-chip bandgap reference, fast bus interface compatible with 8-bit microprocessors, and is housed in a 28-pin plastic DIP package.

Specialized Feature Summary

Complete analog I/O system integrating ADC, DACs, and reference on one chip
Fast microprocessor interface with bus access times under 75 ns
Programmable input/output voltage ranges for single or dual supply operation
On-chip temperature-compensated bandgap reference

Specialized Applications

Microprocessor-based data acquisition systems
Industrial process control interfaces
General-purpose analog signal conditioning

Specialized Procurement Notes

Verify the specific suffix JN corresponds to the 28-pin plastic DIP package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as historical datasheets may predate modern regulations. Ensure ESD precautions are observed during handling due to CMOS construction.

Specialized Selection Notes

Select the AD7669JN when dual DAC outputs are required alongside an 8-bit ADC. Compare against the AD7569 if only a single DAC is needed. Verify that the 8-bit resolution and 400 kHz sampling rate meet system requirements. Check compatibility with existing 8-bit microprocessor bus timing constraints.

Specialized Part Context

The AD7669 is part of the Analog Devices AD7569/AD7669 family of complete analog I/O systems. It shares the same core architecture as the AD7569 but provides two DAC channels instead of one. This family utilizes LC2MOS technology to combine precision bipolar circuits with low power CMOS logic.
