Applications Information
Product Description
The EL1510 is a dual operational amplifier designed for line
driving in DMT ADSL solutions. It is a dual current mode
feedback amplifier with low distortion while drawing
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 EL1510 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.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, good printed circuit
board layout is necessary for optimum performance. Ground
plane construction is highly recommended. Lead lengths
should be as short as possible, below ”. The power supply
pins must be well bypassed to reduce the risk of oscillation.
A 1.0F tantalum capacitor in parallel with a 0.01F ceramic
capacitor is adequate for each supply pin.
For good AC performance, parasitic capacitances should be
kept to a minimum, especially at the inverting input. This
implies keeping the ground plane away from this pin. Carbon
resistors are acceptable, while use of wire-wound resistors
should not be used because of their parasitic inductance.
Similarly, capacitors should be low inductance for best
performance.
