• Product introduction

AD9628BCPZ-105   12位、125/105 MSPS、1.8 V双通道模数转换器

AD9628是一款单芯片、双通道、12位、125/105 MSPSAnalog-to-digital converters(ADC)，采用1.8V电源供电，内置高性能采样保持电路和片内基准电压源。

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。

The ADC includes features that provide optimal flexibility and minimal system cost, such as programmable clock and data alignment, and generation of programmable digital test patterns. Available digital test codes include built-in fixed and pseudo-random codes, as well as user-defined test codes input via the serial port interface (SPI).

A differential clock input is used to control all internal conversion cycles. An optional duty cycle stabilizer (DCS) is used to compensate for large clock duty cycle fluctuations while maintaining excellent overall ADC performance.

数字输出数据格式为偏移二进制、格雷码或二进制补码。每个ADC通道均有一个数据输出时钟(DCO)，用来确保接收逻辑具有正确的锁存时序。支持1.8 V CMOS或LVDS输出逻辑电平。输出数据也可以多路复用到一条输出总线。

AD9628采用64引脚LFCSP封装，符合RoHS标准，额定温度范围为−40°C至+85°C工业温度范围。该产品受美国专利保护。
