AD9216: 10位、65/80/105 MSPS、双核ADC

AD9216 功能框图 AD9216是一款双核、3 V、10位、65/80/105 MSPS模数转换器（ADC）,集成了两个高性能采样保持放大器和一个基准电压源。它采用多级差分流水线架构,内置输出纠错逻辑,在最高105 MSPS数据速率时可提供10位精度,并保证在整个工作温度范围内无失码。利用宽带宽、差分采样保持放大器（SHA）,用户可以选择包括单端应用在内的各种输入范围和偏移。该器件适用于各种应用,包括在连续通道中切换满量程电平的多路复用系统,以及采用远超过Nyquist速率的频率对输入进行采样。采用双单端时钟输入来控制所有内部转换周期。AD9216-65提供一个占空比稳定器,可用来补偿较大的时钟占空比波动,使转换器保持出色的性能。数字输出数据格式为标准二进制或二进制补码。超量程信号表示溢出状况,可由最高有效位来确定是下溢还是上溢。AD9216采用先进的CMOS工艺制造,提供节省空间的64引脚LFCSP（9x9）封装,额定温度范围为-40°C至+85°C工业温度范围。

The AD9216 is a dual, 3 V, 10-bit, 65/80/105 MSPS analog-to-digital converter. It features dual high performance sample and hold amplifiers and an integrated voltage reference. The AD9216 uses a multistage differential pipelined architecture with output error correction logic to provide 10-bit accuracy and guarantee no missing codes over the full operating temperature range at up to 105 MSPS data rates. The wide bandwidth, differential SHA allows for a variety of user selectable input ranges and offsets including single-ended applications. It is suitable for various applications including multiplexed systems that switch full-scale voltage levels in successive channels and for sampling inputs at frequencies well beyound the Nyquist rate.Dual single-ended clock inputs are used to control all internal conversion cycles. A duty cycle stabilizer is available on the AD9216-65 and can compensate for wide variations in the clock duty cycle, allowing the converters to maintain excellent performance. The digital output data is presented in either straight binary or twos complement format. Out-of-range signals indicate an overflow condition, which can be used with the most significant bit to determine low or high overflow.Fabricated on an advanced CMOS process, the AD9216 is available in a space saving 64-lead LFCSP (9x9) and is specified over the industrial temperature range (-40°C to +85°C).
