AD1377JD

Overview

The AD1377JD is a complete, high-speed 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices. 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 on ±15 V analog supplies and a +5 V digital supply, consuming approximately 585 mW of power. It features a maximum linearity error of ±0.006% at 25°C and guarantees no missing codes up to 14 bits across the commercial temperature range of 0°C to 70°C. The AD1377JD provides parallel digital outputs with TTL-compatible logic levels.

Feature Summary

• 16-bit resolution with a maximum nonlinearity error of ±0.006% FSR at 25°C
• Fast conversion time of 10 µs for full 16-bit accuracy
• Integrated internal voltage reference and clock generator
• Laser-trimmed thin-film resistors for precise input scaling ranges
• Guaranteed no missing codes to 14 bits over the 0°C to 70°C operating range

Applications

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

Procurement Notes

Verify the specific date code when sourcing this component, as the serial output function was discontinued after date code 0210. Confirm that the application does not rely on applying an external clock to the CONVERT START pin to slow down conversion times, as this option is no longer supported. Ensure the procurement matches the JD suffix specifications regarding linearity and temperature performance.

Selection Notes

Select the AD1377JD when a 10 µs conversion time is required for 16-bit resolution. Choose this model over the AD1376JD if faster throughput is necessary. Consider the AD1377KD variant if a tighter linearity specification of ±0.003% is required. Verify that the system can accommodate the 32-lead ceramic DIP package and the specific ±15 V and +5 V power supply requirements.

Part Context

The AD1377JD belongs to the AD1376/AD1377 family of monolithic 16-bit ADCs. These devices utilize a successive approximation register (SAR) architecture with an internal DAC. The JD suffix denotes a commercial temperature range (0°C to 70°C) with a maximum linearity error of ±0.006%. This part is distinct from the KD suffix version, which offers improved linearity of ±0.003%, and from earlier revisions that included serial output capabilities.
