AD976AARZ

Analog To Digital Converters (ADC) Overview

The AD976AARZ is a monolithic 16-bit analog-to-digital converter (ADC) from Analog Devices, utilizing successive approximation register (SAR) architecture. It operates with a single 5V supply and features a parallel digital interface for data output. The device supports a sampling rate of 200 kSPS and accepts single-ended voltage inputs. Packaged in a 28-lead SOIC surface-mount format, it integrates both internal and external reference capabilities. Key performance metrics include an integral nonlinearity (INL) of ±3 LSB and a signal-to-noise ratio (SNR) of 85 dB, ensuring high precision for data acquisition applications within the industrial temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm specific ordering suffixes match required packaging and temperature grades. Check current lifecycle status as older ADC models may face obsolescence risks. Ensure compliance with RoHS directives if applicable to your region. Validate pin compatibility before integrating into existing PCB layouts.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and low power consumption are critical. Compare against higher-speed ADCs if sampling rates above 200 kSPS are needed. Consider package size constraints as the 28-SOIC requires adequate board space. Evaluate noise performance requirements against the specified SNR. Ensure the system design accommodates the parallel interface complexity compared to serial alternatives.

Analog To Digital Converters (ADC) Part Context

The AD976AARZ belongs to the AD976 family of high-performance ADCs designed by Analog Devices. This series is known for balancing resolution with power efficiency. The 'AA' suffix typically denotes an extended temperature grade, while 'RZ' indicates a lead-free RoHS-compliant SOIC package. It serves as a bridge between lower-resolution general-purpose converters and specialized high-speed data acquisition chips.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may be limited due to the specific 16-bit SAR architecture. Review datasheets for alternative 16-bit ADCs with similar sampling rates and parallel interfaces. Verify that substitute components meet the same INL and SNR specifications. Check for any changes in reference voltage requirements or power supply configurations.
