电流输出 DAC

Analog Devices 提供了一个宽泛的高精度、乘法电流输出 (IOUT) 数模转换器 (DAC) 系列,其具有 ±1LSB INL 和 DNL 规格以及从 12 位至业界领先之 18 位的分辨率。我们的产品组合包括采用小型封装且具有并行、串行 SPI 或 I2C 接口的单通道和乘法 DAC。电流输出 R-2R DAC 允许选择一个针对特定应用而优化的外部放大器,而且不需要对基准进行缓冲,因而具有高线性度。SoftSpan™ 特性能提供软件可选的输出范围,从而免除了增设精准增益级以及相关联的外部跨接线、精准电阻器和放大器电路的需要。集成化精准电阻器可提供基准反演、双极性偏移、偏移和增益调节。
