The EL2260/EL2460 are dual and quad current mode feedback amplifiers that offer wide bandwidths and good video specifications at moderately low supply currents. They are built using Elantec's proprietary complimentary bipolar process and are offered in industry standard pinouts. Due to the current feedback architecture, the EL2260/EL2460 closed-loop 3dB bandwidth is dependent on the value of the feedback resistor. First the desired bandwidth is selected by choosing the feedback resistor, RF, and then the gain is set by picking the gain resistor, RG. The curves at the beginning of the Typical Performance Curves section show the effect of varying both RF and RG. The 3dB bandwidth is somewhat dependent on the power supply voltage. As the supply voltage is decreased, internal junction capacitances increase, causing a reduction in closed loop bandwidth. To compensate for this, smaller values of feedback resistor can be used at lower supply voltages.
