AD976AANZ

Analog To Digital Converters (ADC) Overview

The AD976AANZ is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates from a single 5 V supply and supports a throughput of 200 kSPS. The device features a parallel interface, single-ended input, and an internal 2.5 V reference. Key electrical specifications include a signal-to-noise ratio of 85 dB, integral nonlinearity of ±3 LSB, differential nonlinearity of -2/3 LSB, and gain error of ±0.5% FSR. Power dissipation is limited to 100 mW, with an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• High-speed 16-bit resolution with 200 kSPS sampling rate
• Single 5 V supply operation with low power consumption
• Integrated 2.5 V voltage reference for simplified design
• Factory calibrated linearity errors

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition modules
• Vibration monitoring equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Check for RoHS compliance suffixes if environmental regulations apply. Confirm package integrity upon receipt as the PDIP-28 tube packaging may be subject to long-term storage conditions. Validate part markings against official datasheet specifications to ensure no counterfeiting.

Analog To Digital Converters (ADC) Selection Notes

Select the AD976AANZ when a 16-bit resolution and 200 kSPS speed are required in a through-hole package. Compare with the AD976ANZ variant which offers 100 kSPS throughput if lower speed suffices. Ensure the system requires a single 5 V supply and can accommodate the parallel interface timing constraints. Verify that the ±10 V input range matches the application signal levels.

Analog To Digital Converters (ADC) Part Context

The AD976AANZ belongs to the AD976 family of BiCMOS A/D converters. It is the higher-speed variant compared to the standard AD976. The 'AA' suffix denotes the SOIC package, while 'ANZ' indicates the PDIP package with lead-free/RoHS compliance. This series represents legacy high-performance ADC technology from Analog Devices.

Analog To Digital Converters (ADC) Replacement Considerations

The AD976ANZ is a compatible alternative offering 100 kSPS throughput. The AD976ARZ provides the same performance in an SOIC surface-mount package. No direct modern pin-compatible replacements exist; redesign may be necessary for newer technologies.
