coupled, via a coupling capacitor to the inverting input, then the bias current will flow through the feedback resistor R F alone, and the value of R F is set to infinity in the calculation. In this case, the bias current will flow through both R 1 and the feedback resistor R F.If the source is a.c. If an inverting configuration is used, then R 1 represents the d.c. coupled, via a coupling capacitor to the non-inverting input, then this resistor must be included to provide a d.c. If a non-inverting configuration is used, then R 2 represents the d.c. The increase is equal to the bias terminal voltage divided by this resistance.

Note 5: With the TO-3 and TO-220 packages, output stage quiescent current can be increased by connecting a resistor between the bias pin and V +. See applications information for determining available output swing and input drive requirements for a given load. Note 4: The output saturation characteristics are measured with 100mV output clipping.

and boldface type on limits denote the specifications that apply over the full temperature range.Note 3: Specifications apply for 4.5V ≤ V S ≤ 40V, V − + 0.5V ≤ V IN ≤ V + – 1.5V and I OUT = 0, unless otherwise stated. Input current also rises rapidly for input voltages 8V above V + or 0.5V below V −. Note 2: In current limit or thermal limit, input current increases sharply with input-output differentials greater than 8V so input current must be limited.

Note 1: For case temperatures above 25☌, dissipation must be derated based on a thermal resistance of 25☌/W with the K and T packages or 40☌/W with the H package.
