1、描述此 TI 精密验证设计为特定差动输出电路的单端输入提供了原理、组件选择、仿真、PCB 设计和测量细节，其中的差动输出电路可将+0.1V 至+2.4V 的单端输入转换为+2.7V 单电源上的 2.3V 差动输出。输出范围经特别限定以使其线性度最大化。此电路包括 2 个放大器。一个放大器充当缓冲器，创建电压 Vout+。第二个放大器使输入反向并增加基准电压以产生 Vout-。Vout+和 Vout-的范围均为 0.1V 至 2.4V。电压差 Vdiff 是 Vout+与Vout-之间的差值。这将使差动输出电压范围+2.3V。特性100kHz 小信号带宽低功耗：100mA 电流消耗0.1%FSR
