Overview
The AD779JNZ is a 14-bit sampling analog-to-digital converter (ADC) from the Analog Devices AD779 series. It utilizes a Flash architecture and features a single-channel, single-ended input type. The device supports a parallel digital interface and achieves a sampling rate of 128 kS/s. It operates within a temperature range of 0°C to +70°C and is housed in a 28-pin PDIP package for through-hole mounting. Key performance specifications include a gain error of 0.12% FSR and an integral nonlinearity (INL) of 2 LSB. The component consumes 560 mW of power and accepts both external and internal reference types.
Feature Summary
- Flash-based conversion architecture for high-speed data acquisition
- Integrated sample-and-hold circuitry for signal stability
- Flexible reference configuration supporting internal or external sources
Applications
- High-speed industrial process control systems
- Precision measurement instrumentation requiring fast sampling
- Data acquisition modules with parallel bus interfaces
Procurement Notes
Verify current availability status as supply may be restricted. Confirm that the PDIP-28 package and parallel interface requirements align with the target PCB design. Ensure voltage levels for the parallel interface match the system logic standards before integration.
Selection Notes
Select this component when a 14-bit resolution and 128 kS/s throughput are required with a parallel interface. Consider the 560 mW power dissipation and thermal management needs for the application environment. Verify compatibility with single-ended input signals and the specific operating temperature range of 0°C to +70°C.
Part Context
The AD779JNZ belongs to the AD779 family of data converters. This series includes various ADC models with different resolutions and interface options. The J suffix typically denotes the commercial temperature grade, while NZ indicates lead-free packaging compliance.
Replacement Considerations
The AD779KNZ is identified as a direct substitute part number. Note that the AD779KNZ has been marked as obsolete and no longer manufactured.
