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 AD9057 includes an internal 2.5 V reference and a track-and-hold (T/H) circuit. The user must provide only a 5 V power supply and an encode clock. No external reference or driver components are required for many applications.
