Power Supplies
The power supplies should be well bypassed close to the
EL1504/5C. A 3.3
F tantalum capacitor for each supply
works well. Since the load currents are differential, they
should not travel through the board copper and set up
ground loops that can return to amplifier inputs. Due to
the class AB output stage design, these currents have
heavy harmonic content. If the ground terminal of the
positive and negative bypass capacitors are connected to
each other directly and then returned to circuit ground,
no such ground loops will occur. This scheme is
employed in the layout of the EL1504/5C demonstration
board, and documentation can be obtained from the
factory.
Feedback Resistor Value
The bandwidth and peaking of the amplifiers varies with
supply voltage and gain settings. The drivers can be used
for a wide range of gains. The feedback resistor values
can be adjusted to produce an optimal frequency
response. Here is a series of resistor values that produce
an optimal driver frequency response (1 dB peaking) for
different supply voltages and gains:
Driving Video Loads
Each driver can drive four double-terminated video
loads while operating on ±5V supplies. Larger supply
voltages slightly improve differential gain and phase
distortions, which are around 0.2% and 0.1° for single-
ended outputs with the standard NTSC test.
