rejections. Worst-case summation of guaranteed
specifications is tabulated below.
Large Signal Voltage Follower
With 0.001% Worst Case Accuracy
The voltage follower is an ideal example illustrating
the overall excellence of the LT1001. The contributing
error terms are due to offset voltage, input bias cur-
rent, voltage gain, common mode and power-supply
