AD9057: 8位、40/60/80 MSPS ADC

AD9057 功能框图AD9057是一款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40 MSPS、60 MSPS或80 MSPS编码速率及120 MHz全功率模拟带宽,非常适合要求出色动态性能的应用。为使系统成本和功耗达到最低,AD9057内置了一个+2.5 V基准电压源和采样保持电路。用户只需提供一个+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。AD9057的编码输入为TTL/CMOS兼容,8位数字输出可以采用+5 V或+3 V电源供电。可通过进入节电模式,将总功耗降至10 mW以下。在节电模式下,数字输出被置为高阻抗状态。AD9057采用先进的BiCMOS工艺制造,提供节省空间的20引脚表贴塑封封装(20 SSOP),额定温度范围为-40°C至+85°C工业温度范围。需要执行多通道数字转换的客户可以考虑AD9059,它是基于AD9057 ADC内核的双通道、8位、60 MSPS单芯片ADC。AD9059采用28引脚表贴塑封封装(28 SSOP),额定温度范围为工业温度范围。

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 package (20 SSOP) and is specified over the industrial (-40°C to +85°C) temperature range.Customers desiring multichannel digitization may consider the AD9059, a dual 8-bit, 60 MSPS monolithic based on the AD9057 ADC core. The AD9059 is available in a 28-lead surface mount plastic package (28 SSOP) and is specified over the industrial temperature range。
