The AD9215 is a family of monolithic, single 3 V supply, 10-bit, 65/80/105 MSPS analog-to-digital converters. This family features a high-performance sample-and-hold amplifier and voltage reference. The AD9215 uses a multistage differential pipelined architecture with output error correction logic to provide 10-bit accuracy at 105 MSPS data rates and guarantee no missing codes over the full operating temperature range.
The wide-bandwidth, truly differential sample and hold amplifier (SHA) allows for a variety of user-selectable input ranges and offsets including single-ended applications. It is suitable for multiplexed systems that switch full-scale voltage levels in successive channels and for sampling single-channel inputs at frequencies well beyond the Nyquist range. Combined with power and cost savings over previously available analog-to-digital converters, the AD9215 is suitable for applications in communications, imaging, and medical ultrasound.
A single-ended clock input is used to control all internal conversion cycles. A duty cycle stabilizer compensates for wide variations in the clock duty cycle while maintaining excellent performance. The digital output data is presented in straight binary or twos complement formats. An out-of-range signal indicates 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 AD9215 is available in both a 28-lead surface-mount plastic package and a 32-lead chip-scale package, and is specified over the industrial temperature range (-40°C to +85°C).
AD9215属于单芯片、10位、65/80/105 MSPS模数转换器（ADC）系列,采用3 V单电源供电,该系列均内置一个高性能采样保持放大器和基准电压源。AD9215采用多级差分流水线架构,内置输出纠错逻辑,在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、真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范围的频率对单通道输入进行采样。与以前的模数转换器相比,AD9215的功耗与成本均有所降低,适用于通信、成像和医疗超声等应用。
采用一个单端时钟输入来控制所有内部转换周期。一个占空比稳定器用来补偿较大的时钟占空比波动,同时保持出色的性能。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。
AD9215采用先进的CMOS工艺制造,提供28引脚表面贴装塑料封装和32引脚芯片级封装,额定温度范围为-40°C至+85°C工业温度范围。
