ADI’s AD9694 is a quad, 14-bit, 500-MSPS analog-to-digital converter (ADC). The device has an on-chip buffer, sample, and hold circuit designed for low power, small size, and ease-of-use. The AD9694 is designed for sampling wide bandwidth analog signals of up to 1.4 GHz. The part is optimized for wide input bandwidth, high sampling rates, excellent linearity, and low power in a small package.

The quad ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs, supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations.
