Applications Information
Product Description
The EL1509 is a dual operational amplifier designed for
customer premise 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 EL1509 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.
