The AD976 and AD976A are high-speed, low-power 16-bit A/D converters with each operating from a single 5 V supply. The AD976A has a throughput rate of 200 ksps whereas the AD976 has a throughput rate of 100 ksps. Each part contains a successive approximation, switched capacitor ADC, an internal 2.5 V reference, and a high-speed parallel interface. The AD976 and AD976A dissipate a maximum of 100 mW. The ADC is factory calibrated to minimize all linearity errors. The analog full-scale input is the standard industrial range of ±10 V.

The AD976 and AD976A are comprehensively tested for ac parameters such as SNR and THD, as well as the more traditional parameters of offset, gain and linearity.

The AD976 and AD976A are fabricated on Analog Devices' proprietary BiCMOS process, which has high performance bipolar devices along with CMOS transistors.

The AD976 and AD976A are available in skinny 28-pin DIP, SSOP and SOIC packages.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
