PRODUCT DESCRIPTION The AD9057 is an 8-bit monolithic analog-to-digital converter optimized for low cost, low power, small size, and ease of use. With 40 MSPS, 60 MSPS, or 80 MSPS encode rate capability and full-power analog bandwidth of 120 MHz, the component is ideal for applications requiring excellent dynamic performance.
To minimize system cost and power dissipation, the AD.
