AD9059:双核、8位、60 MSPS ADC

AD9059: 双核、8位、60 MSPS ADC

AD9059是一款双核8位单芯片模数转换器（ADC），专门针对低成本、低功耗、小尺寸和易用性进行了优化。该器件提供60 MSPS编码速率和120 MHz（典型值）全功率模拟带宽，非常适合需要多个具有出色动态性能ADC的应用。为使系统成本和功耗达到最低，AD9059内置了一个+2.5 V基准电压源和双采样保持电路。该ADC只需一个+5 V电源和一个编码时钟。对于大多数应用来说，无需外部基准电压源或驱动器件。AD9059的单编码输入为TTL/CMOS兼容，并且同时控制ADC的两个内部通道。并行8位数字输出可以采用+5 V或+3 V电源供电。当长时间不需要ADC数据时，可进入省电模式，以便将总功耗降至12 mW以下。在省电模式下，数字输出被置为高阻状态。AD9059采用先进的BiCMOS工艺制造，提供节省空间的28引脚表面贴装塑料封装（28 SSOP），额定温度范围为-40°C至+85°C工业温度范围。需要执行单通道数字转换的客户可以考虑AD9057，它是基于AD9059 ADC内核的单通道、8位、60 MSPS单芯片ADC。AD9057采用20引脚表面贴装塑料封装（20 SSOP），额定温度范围为工业温度范围。

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 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 surface mount plastic package (20 SSOP) and is specified over the industrial temperature range.
