AD1376JD

Overview

The AD1376JD is a complete, high-speed 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It integrates an internal reference, clock, and laser-trimmed thin-film scaling resistors within a hermetic 32-lead ceramic DIP package. The device supports bipolar input ranges of ±2.5 V, ±5 V, and ±10 V, as well as unipolar ranges of 0 V to +5 V, 0 V to +10 V, and 0 V to +20 V. Key electrical specifications include a maximum linearity error of ±0.006% at 25°C, a typical conversion time of 17 µs for full 16-bit resolution, and typical power consumption of 645 mW. Digital outputs are provided in parallel form with TTL-compatible logic levels.

Feature Summary

• Complete 16-bit resolution with integrated reference and clock
• Maximum nonlinearity error of ±0.006% at 25°C
• Parallel digital output with complementary binary coding options
• Hermetic 32-lead ceramic dual in-line package (DIP)

Applications

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

Procurement Notes

Verify the specific date code when sourcing this component, as the serial output function was discontinued for the AD1376 series after date code 0111. Confirm that the application design does not rely on applying an external clock to the CONVERT START pin, as this option is no longer supported. Ensure the procurement matches the JD suffix requirements for the specified temperature range and linearity performance.

Selection Notes

Select the AD1376JD over the AD1377 variant if the system timing budget accommodates the slower 17 µs conversion time for full 16-bit resolution. The JD suffix indicates a maximum linearity error of ±0.006%, which is suitable for general high-resolution applications but less precise than the KD version's ±0.003%. Consider short-cycle capabilities if lower resolution (e.g., 14 bits) allows for faster throughput requirements within the same hardware constraints.

Part Context

The AD1376/AD1377 series represents a family of monolithic 16-bit successive approximation register (SAR) converters. The AD1376JD is the commercial temperature grade variant with standard linearity specifications. It shares the same physical footprint and pinout with the AD1377JD, differing primarily in internal clock speed and conversion latency. Both utilize laser-trimmed thin-film resistors to ensure stability and accuracy without requiring extensive external calibration components.

Replacement Considerations
