AD976ACNZ

Analog To Digital Converters (ADC) Overview

The AD976ACNZ 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 features a throughput rate of 200 kSPS. The device includes an internal 2.5 V reference and supports a parallel interface with on-chip clock generation. It accepts a ±10 V full-scale input range and is housed in a 28-lead SOIC package. Key performance metrics include a signal-to-noise ratio of 85 dB, differential nonlinearity of ±2 LSB, integral nonlinearity of ±3 LSB, and gain error of ±0.5% FSR. Power dissipation is limited to 100 mW, and it functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed parallel interface with on-chip clock generation for simplified system design.
• Factory calibrated to minimize linearity errors across the operating temperature range.
• Supports flexible reference configuration with options for both external and internal 2.5 V references.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions meet humidity sensitivity requirements to prevent package degradation during handling and assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 16-bit resolution and 200 kSPS sampling rate are required with a parallel interface. The single 5 V supply capability simplifies power management compared to dual-supply alternatives. Consider the SOIC package format for surface-mount applications where space constraints exist relative to DIP packages.

Analog To Digital Converters (ADC) Part Context

The AD976ACNZ belongs to the AD976 family of BiCMOS A/D converters. This series distinguishes itself by combining high speed with low power consumption. The 'A' suffix typically denotes the 200 kSPS speed grade, while 'CNZ' indicates the commercial temperature range and lead-free SOIC packaging variant within the product lineup.

Analog To Digital Converters (ADC) Replacement Considerations

The AD976ANZ serves as a direct pin-compatible replacement offering identical electrical specifications. Verify that any substitute maintains the same 200 kSPS throughput and 16-bit resolution to ensure circuit compatibility without redesign.
