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 dy- namic 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 to- tal 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 surface mount plastic package (28 SSOP) and is specified over the industrial (–40 °C to +85°C) temperature range. 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 sur- face mount plastic package (20 SSOP) and is specified over the industrial temperature range.
