关于tlv5616，请指教

我用2.5v的参考输入

为什么最大输出也是2.5V

没有实现2倍放大？

谢谢各位。

你好, TLV5616是一个DAC.

注意下面描述

The output voltage (full scale determined by external reference) is given by:
2 REF CODE/2n [V]
where REF is the reference voltage and CODE is the digital input value within the range of 010 to 2n−1, where
n = 12 (bits).
