The AD775 is a CMOS, low power, 8-bit, 20 Msps sampling analog-to-digital converter (ADC). The AD775 features a built-in sampling function and on-chip reference bias resistors to provide a complete 8-bit ADC solution. The AD775 utilizes a pipelined/ping pong two-step flash architecture to provide high sampling rates (up to 35 MHz) while maintaining very low power consumption (60 mW).

Its combination of excellent DNL, fast sampling rate, low diferential gain and phase errors, extremely low power dissipation, and single +5 V supply operation make it ideally suited for a variety of video and image acquisition applications, including portable equipment. The AD775's reference ladder may be connected in a variety of configurations to accomodate different input ranges. The low input capacitance (11 pF typical) provides an easy-to-drive input load compared to conventional flash converters.

The AD775 is offered in both 300 mil SOIC and 400 mil DIP plastic packages, and is designed to operate over an extended commercial temperature range (-20°C to +75°C).

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• Obsolete: The specific part is obsolete and no longer available.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.
