AD976ABNZ

Analog To Digital Converters (ADC) Overview

The AD976ABNZ is a 16-bit resolution, single-channel Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It utilizes a Successive Approximation Register (SAR) architecture and supports a sampling rate of 200 kS/s with a parallel interface. The device operates on dual 5 V analog and digital power supplies, drawing 100 mW of power dissipation. Key performance metrics include an SNR of 85 dB, DNL of -1 LSB/1.75 LSB, INL of +/- 2 LSB, and gain error of +/- 0.25% FSR. It accepts single-ended voltage inputs and is housed in a 28-lead PDIP package suitable for through-hole mounting across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm specific suffix requirements against original design specifications since ordering suffixes may indicate variations in packaging or testing standards without altering core functionality. Request manufacturer datasheets to validate pin compatibility and electrical characteristics before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring 16-bit resolution at moderate speeds up to 200 kS/s. Ensure the application can accommodate the 28-pin PDIP footprint and through-hole assembly process. Verify that the system power budget aligns with the 100 mW dissipation requirement and that the 5 V supply rails are available for both analog and digital domains.

Analog To Digital Converters (ADC) Part Context

The AD976ABNZ belongs to the AD976A series of monolithic 16-bit ADCs from Analog Devices. This family is characterized by CMOS technology and offers a balance between resolution and speed for general-purpose applications. The ABNZ suffix typically denotes a specific grade or packaging variant within the broader AD976 product line, maintaining compatibility with other devices in the same architectural family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements are limited due to the obsolete status. Consider evaluating newer members of the ADI SAR ADC portfolio, such as the AD40xx series, which offer improved performance metrics and modern packaging options while maintaining similar resolution and interface types.
