AD9233BCPZ-125:  12位、80 MSPS/105 MSPS/125 MSPS、1.8 V模数转换器

The AD9233 is a monolithic, single 1.8 V supply, 12-bit, 80 MSPS/ 105 MSPS/125 MSPS analog-to-digital converter (ADC), featuring a high performance sample-and-hold amplifier (SHA) and on-chip voltage reference. The product uses a multistage differential pipeline architecture with output error correction logic to provide 12-bit accuracy at 125 MSPS data rates and guarantees no missing codes over the full operating temperature range.

The wide bandwidth, truly differential SHA allows 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 rate. Combined with power and cost savings over previously available ADCs, the AD9233 is suitable for applications in communications, imaging, and medical ultrasound.

A differential clock input controls all internal conversion cycles. A duty cycle stabilizer (DCS) compensates for wide variations in the clock duty cycle while maintaining excellent overall ADC performance.

The digital output data is presented in offset binary, Gray code, or twos complement formats. A data output clock (DCO) is provided to ensure proper latch timing with receiving logic.

The AD9233 is available in a 48-lead LFCSP and is specified over the industrial temperature range (−40°C to +85°C).

AD9233是一款单芯片、12位、80 MSPS/ 105 MSPS/125 MSPS模数转换器（ADC）,采用1.8 V单电源供电,内置一个高性能采样保持放大器（SHA）和片内基准电压源。该产品采用多级差分流水线架构,内置输出纠错逻辑,在125 MSPS数据速率时可提供12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速率的频率对单通道输入进行采样。与以前的模数转换器相比,AD9233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。

采用一个差分时钟输入来控制所有内部转换周期。一个占空比稳定器（DCS）用来补偿较大的时钟占空比波动,同时保持出色的ADC总体性能。

数字输出数据格式为偏移二进制、格雷码或二进制补码。一个数字输出时钟（DCO）用来确保接收逻辑具有正确的锁存定时。

AD9233采用48引脚LFCSP封装,额定温度范围为−40°C至+85°C工业温度范围。
