AD1377KD

Overview

The AD1377KD is a high-resolution, 16-bit analog-to-digital converter manufactured by Analog Devices Inc. It integrates an internal reference, clock, and laser-trimmed thin-film scaling resistors within a compact 32-lead ceramic seam-sealed dual in-line package (DIP). The device operates with ±15 V analog supplies and a +5 V digital supply, consuming approximately 585 mW of power. It features a maximum linearity error of ±0.003% at 25°C and guarantees no missing codes up to 14 bits across the commercial temperature range of 0°C to 70°C. The AD1377KD provides parallel digital outputs compatible with TTL logic levels.

Feature Summary

• 16-bit resolution with ±0.003% maximum nonlinearity error at 25°C
• Fast conversion time of 10 µs for full 16-bit accuracy
• Integrated internal reference and clock with external rate adjustment capability
• Supports short-cycle operation for reduced resolution and faster throughput

Applications

• Medical and analytical instrumentation
• Precision measurement for industrial robotics
• Automatic test equipment (ATE)
• Multichannel data acquisition systems
• Servo control systems requiring wide dynamic range

Procurement Notes

Verify the specific ordering suffix KD against the manufacturer's current documentation to confirm the ±0.003% linearity specification and commercial temperature range. Ensure the procurement source provides the DH-32E ceramic DIP package variant. Confirm that the date code aligns with the Rev. D datasheet specifications, particularly regarding the removal of serial output functionality.

Selection Notes

Select the AD1377KD when high accuracy and stability are required over the 0°C to 70°C commercial temperature range. Choose this model over the JD variant if the application demands a maximum linearity error of ±0.003%. Consider the 10 µs conversion time for moderate speed requirements. Verify that the system can accommodate the ±15 V analog supply rails and the specific input scaling connections required for the desired voltage range.

Part Context

The AD1377KD belongs to the AD1376/AD1377 family of complete, high-speed 16-bit A/D converters. These devices utilize a successive approximation register architecture with a proprietary monolithic DAC and laser-trimmed thin-film resistors. The KD suffix denotes the higher precision grade with improved linearity characteristics compared to the standard JD grade, both sharing the same hermetic ceramic DIP packaging.
