12.1.1 器件命名规则

    REAOPC

    一点校准后的残余误差是由于组成信号处理块的错误在模拟信号路径中得到的误差:其中的组成信号处理块有 DAC,缓冲放大器,内部基准。 REAOPC 主要由偏移和增益温度漂移决定,这是因为初始误差的绝大部分在一点校准的过程中被消除。 DAC 线性误差 (INL) 所造成的误差可被忽略,这是因为这个误差在数量上微不足道。 通过以下公式可预计 REAOPC:

    一点校准

    一点校准是 LMP92066 的输出在系统中被调整,以实现所需响应的过程,此时温度为 T0。 通常情况下,这个过程涉及总体系统输出变量的测量;例如,PA 的 ID,在 LUT 中修改 BASE 值,以实现所需的 PA 偏置电流。
