Description

Datasheet this example, examining the specifications for the OPA227 , shows that a frequency range of 0.1 Hz Thus, the TINA-TI model for the OPA227 accurately models. The figure on the right is from the OPA227 data sheet. Note that the data sheet curve is referred to the input. To make the plot on the left referred to the input OPA227 in Unity-Gain Buffer Configuration limiting feedback resistor. BASIC NOISE CALCULATIONS.
