AD1380KD

Overview

The AD1380KD is a complete, low-cost 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It integrates an internal reference voltage, clock generator, and sample-and-hold amplifier (SHA). The device features a maximum linearity error of ±0.003% of full-scale range (FSR) and supports input ranges including ±2.5 V, ±5 V, ±10 V, 0 V to +5 V, and 0 V to +10 V. It operates with a maximum throughput of 50 kHz and consumes 900 mW of power. Digital outputs are TTL-compatible, providing parallel data with corresponding clock and status signals in a 32-lead hermetic ceramic DIP package.

Feature Summary

• Integrated 16-bit successive-approximation ADC with internal reference, clock, and SHA
• Maximum linearity error of ±0.003% FSR for the AD1380KD variant
• Supports multiple analog input ranges: ±2.5 V, ±5 V, ±10 V, 0 V to +5 V, and 0 V to +10 V
• Parallel digital output with TTL/5 V CMOS compatibility and 50 kHz maximum throughput

Applications

• Medical and analytical instrumentation
• Signal processing systems
• Data acquisition systems
• Professional audio equipment
• Automatic test equipment (ATE)

Procurement Notes

The AD1380KD is listed as obsolete in official documentation. Verification of current availability requires checking authorized distributors or surplus suppliers. Ensure the component meets RoHS compliance requirements if applicable to the specific procurement batch, as indicated by manufacturer records.

Selection Notes

Select the AD1380KD when high linearity (±0.003% FSR) and integrated signal conditioning are required for 16-bit resolution applications. Consider external calibration circuits for gain and offset adjustments if precision beyond factory specifications is needed. Verify that the 32-lead ceramic DIP package fits the target PCB layout constraints.

Part Context

The AD1380 series includes the AD1380JD and AD1380KD variants, differentiated primarily by linearity error specifications. The KD version offers tighter linearity performance (±0.003% FSR) compared to the JD version (±0.006% FSR). Both share identical electrical characteristics, pinouts, and functional capabilities within the specified temperature range.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the component is obsolete, alternative solutions require evaluating modern 16-bit ADCs with similar interface requirements and performance metrics.
