Linear公司的参考电压的定义是谨慎和准确的，不象其他一些制造商那样意图误导或忽略关键说明以掩盖其缺点，这些缺点可能导致大的错误。LT1461和LT1790是这些器件中的一个，既没有漏掉也没有隐瞒其性能 advertisement Don't Be Fooled By Voltage Reference Long-Term Drift and Hysteresis Design Note 229 John Wright The new micropower LT1461 and LT1790 low dropout reference, this corresponds to a 0.39V shift after 1000 bandgap voltage references excel not only in temperature hours. This is pretty hard to determine (read impossible) coefficient and accuracy, but also in long-term drift and if the peak-to-peak output noise is larger than this num- hysteresis (output voltage shift due to temperature cy- ber. As a practical matter, one of the best laboratory cling). Long-term drift and hysteresis, which are some- re……
