AD9244是一款单芯片、14位、65 MSPS模数转换器(ADC),采用5 V单电源供电,内置一个片内高性能采样保持放大器和基准电压源。它采用多级差分流水线架构,内置输出纠错逻辑,在65 MSPS数据速率时可提供14位精度,并保证在整个工作温度范围内无失码。AD9244具有一个片上可编程基准电压源。也可以选用外部基准电压,以满足应用的直流精度与温度漂移要求。采用一个差分时钟输入来控制所有内部转换周期。数字输出数据格式为标准二进制或二进制补码。超量程(OTR)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。AD9244采用先进的CMOS工艺制造,提供48引脚表面贴装塑料封装(48-LQFP),额定温度范围为-40°C至+85°C工业温度范围。
The AD9244 is a monolithic, single 5 V supply, 14-bit, 65 MSPS analog-to-digital converter with an on-chip, high performance, sample and hold amplifier and voltage reference. The AD9244 uses a multi-stage differential pipelined architecture with output error correction logic to provide 14-bit accuracy at 65 MSPS data rates and guarantees no missing codes over the full operating temperature range.The AD9244 has an on-board, programmable voltage reference. An external reference can also be chosen to suit the DC accuracy and temperature drift requirements of the application.A differential clock input is used to control all internal conversion cycles. The digital output data can be presented in straight binary or in twos complement format. An out of range (OTR) 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 AD9244 is available in a 48 pin surface mount plastic package (48-LQFP) and is specified for operation over the industrial temperature range of (-40°C to +85°C).
