The AD9057 is an 8-bit monolithic analog-to-digital converter optimized for low cost, low power, small size, and ease of use. With a 40 MSPS, 60 MSPS, or 80 MSPS encode rates 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 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. The AD9057's encode input is TTL/CMOS compatible and the 8-bit digital outputs can be operated from 5 V or 3 V supplies. A power-down function may be exercised to bring total consumption to < 10 mW. In power-down mode the digital outputs are driven to a high impedance state. Fabricated on an advanced BiCMOS process, the AD9057 is available in a space saving 20-lead surface mount plastic pack- age (20 SSOP) and is specified over the industrial (40°C to +85°C) temperature range.
