EL1510  
Capacitance at the Inverting Input  
Supply Voltage Range and Operation  
Due to the topology of the current feedback amplifier, stray  
capacitance at the inverting input will affect the AC and  
transient performance of the EL1510 when operating in the  
non-inverting configuration.  
The EL1510 has been designed to operate with supply  
voltages from ±2.5V to ±12V. If a single supply is desired,  
values from +5V to +24V can be used as long as the input  
common mode range is not exceeded. When using a single  
supply, be sure to either 1) DC bias the inputs at an  
appropriate common mode voltage and AC couple the  
signal, or 2) ensure the driving signal is within the common  
mode range of the EL1510.  
In the inverting gain mode, added capacitance at the  
inverting input has little effect since this point is at a virtual  
ground and stray capacitance is therefore not “seen” by the  
amplifier.  
ADSL CPE Applications  
Feedback Resistor Values  
The EL1510 is designed as a line driver for ADSL CPE  
modems. It is capable of outputting 400mA of output current  
with a typical supply voltage headroom of 1.8V. It can  
achieve -85dBc of distortion at low 7.5mA of supply current  
per amplifier.  
The EL1510 has been designed and specified with  
R =1.5kΩ for A =+5. This value of feedback resistor yields  
F
V
extremely flat frequency response with no peaking out to  
40MHz. As is the case with all current feedback amplifiers,  
wider bandwidth, at the expense of slight peaking, can be  
obtained by reducing the value of the feedback resistor.  
Inversely, larger values of feedback resistor will cause rolloff  
to occur at a lower frequency. See the curves in the Typical  
Performance Curves section which show 3dB bandwidth and  
peaking vs frequency for various feedback resistors and  
various supply voltages.  
The average line power requirement for the ADSL CPE  
application is 13dBm (20mW) into a 100Ω line. The average  
line voltage is 1.41V  
. The ADSL DMT peak to average  
RMS  
ratio (crest factor) of 5.3 implies peak voltage of 7.5V into the  
line. Using a differential drive configuration and transformer  
coupling with standard back termination, a transformer ratio  
of 1:1 is selected. The circuit configuration is as shown  
below.  
Bandwidth vs Temperature  
Whereas many amplifiers’ supply current and consequently  
3dB bandwidth drop-off at high temperature, the EL1510  
was designed to have little supply current variations with  
temperature. An immediate benefit from this is that the 3dB  
bandwidth does not drop off drastically with temperature.
