产品详情

AD5429/AD5439/AD5449 分别是 CMOS、8 位、10 位和 12 位双通道电流输出数模转换器 (DAC)。这些器件采用 2.5 V 至 5.5 V 电源供电,非常适合电池供电和其他应用。

由于采用 CMOS 亚微米工艺制造,这些部件具有出色的 4 象限乘法特性,具有 10 MHz 的大信号乘法带宽。

施加的外部参考输入电压 (V REF ) 决定了满量程输出电流。集成反馈电阻器 (RFB) 与外部电流电压精密放大器结合使用时,可提供温度跟踪和满量程电压输出。

这些 DAC 使用与 SPI、QSPI™ 、MICROWIRE 和大多数 DSP 接口标准兼容的双缓冲 3 线串行接口。此外,串行数据输出 (SDO) 引脚允许在使用多个封装时进行菊花链连接。数据回读允许用户通过 SDO 引脚读取 DAC 寄存器的内容。上电时,内部移位寄存器和锁存器用 0 填充,DAC 输出为零。

AD5429/AD5439/AD5449 DAC 采用 16 引脚 TSSOP 封装。 EV-AD5415/49SDZ 评估板可用于评估 DAC 性能。如需更多信息,请参阅 UG-297 评估板用户指南。
