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