The AD9059 is a dual 8-bit monolithic analog-to-digital converter optimized for low cost， low power， small size， and ease of use. With a 60 MSPS encode rate capability and full-power analog bandwidth of 120 MHz typical， the component is ideal for applications requiring multiple ADCs with excellent dynamic performance. To minimize system cost and power dissipation， the AD9059 includes an internal 2.5 V reference and dual track-and-hold circuits. The ADC requires only a 5 V power supply and an encode clock. No external reference or driver components are required for many applications. The AD9059’s single encode input is TTL/CMOS compatible and simultaneously controls both internal ADC channels. The parallel 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 《12 mW when ADC data is not required for lengthy periods of time. In power-down mode， the digital outputs are driven to a high impedance state. Fabricated on an advanced BiCMOS process， the AD9059 is available in a space-saving 28-lead shrink small outline package （28-lead SSOP） and is specified over the industrial temperature range （–40°C to +85°C）。 Customers desiring single-channel digitization may consider the AD9057， a single 8-bit， 60 MSPS monolithic based on the AD9059 ADC core. The AD9057 is available in a 20-lead shrink small outline package （20-lead SSOP） and is specified over the industrial temperature range.
