Product Description
The EL2160 is a current mode feedback amplifier that offers
wide bandwidth and good video specifications at a
moderately low supply current. It is built using Elantec's
proprietary complimentary bipolar process and is offered in
industry standard pin-outs. Due to the current feedback
architecture, the EL2160 closed-loop 3dB bandwidth is
dependent on the value of the feedback resistor. First the
desired bandwidth is selected by choosing the feedback

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.
