Overview
The AD1380JD is a complete, low-cost 16-bit sampling analog-to-digital converter (ADC) housed in a 32-lead hermetic ceramic DIP package. It integrates an internal reference, clock generator, and sample-and-hold amplifier (SHA). The device supports parallel output with TTL-compatible logic levels and offers input ranges of ±2.5 V, ±5 V, ±10 V, 0 V to +5 V, and 0 V to +10 V. Key electrical specifications include a maximum conversion time of 14 μs, a throughput rate of 50 kHz, and a typical noise level of 85 μV rms for unipolar inputs. Power dissipation is rated at 900 mW under standard operating conditions.
Feature Summary
- Integrated 16-bit successive-approximation ADC with internal reference and SHA
- Parallel digital output with complementary binary coding and status flags
- Adjustable gain and zero offset via external trim circuits
- Hermetic 32-lead ceramic DIP packaging for industrial reliability
Applications
- Medical and analytical instrumentation
- Automatic test equipment (ATE)
- Data acquisition systems
- Professional audio processing
Procurement Notes
The AD1380JD is designated as obsolete by Analog Devices. Verification of current availability requires checking authorized distributors or surplus suppliers. Ensure the specific ordering suffix JD corresponds to the 0°C to 70°C temperature range and 0.006% FSR linearity error specification before procurement.
Selection Notes
Select the AD1380JD when a hermetic ceramic package is required for environmental protection. This model provides a maximum linearity error of 0.006% FSR, suitable for applications where moderate precision is sufficient. For higher accuracy, consider the AD1380KD variant which offers 0.003% FSR linearity. Verify that the 50 kHz throughput meets system timing requirements.
Part Context
The AD1380 belongs to a family of low-cost 16-bit sampling ADCs from Analog Devices. The JD suffix specifically denotes the commercial temperature grade (0°C to 70°C) and the standard linearity performance tier within the product line. The device utilizes monolithic thin-film-on-silicon scaling resistors to achieve its specified analog input ranges and linearity characteristics.
Replacement Considerations
As the AD1380JD is obsolete, direct replacements may not be available. Evaluate modern SAR ADCs with similar resolution and interface requirements. Check for pin-compatible alternatives if board space is constrained, though legacy ceramic DIP packages are rarely matched by current surface-mount technologies.
FAQ
What is the maximum linearity error for the AD1380JD?
The AD1380JD has a maximum linearity error of 0.006% of Full Scale Range (FSR).
How is the serial output function handled in this component?
The serial output function was removed after date code 0120. The AD1380JD relies exclusively on parallel data output.
What are the supported analog input voltage ranges?
The device supports bipolar ranges of ±2.5 V, ±5 V, and ±10 V, as well as unipolar ranges of 0 V to +5 V and 0 V to +10 V.
