voltage, plus the power in the IC due to the load, or as
represented in Equation 5:
Where:
VSTOT = Total supply voltage = VS+ - VS-
ISMAX = Maximum quiescent supply current per channel
ΔVO = Maximum differential output voltage of the application
RLD = Differential load resistance
ILOAD = Load current
i = Number of channels
By setting the two PDMAX equations equal to each other, we can
solve the output current and RLOAD to avoid the device overheat.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, a good printed circuit board
layout is necessary for optimum performance. Lead lengths
should be as sort as possible. The power supply pin must be well
bypassed to reduce the risk of oscillation. For normal single
supply operation, where the VS- pin is connected to the ground
plane, a single 4.7F tantalum capacitor in parallel with a 0.1F
ceramic capacitor from VS+ to GND will suffice. This same
capacitor combination should be placed at each supply pin to
ground if split supplies are to be used. In this case, the VS- pin
becomes the negative supply rail.
For good AC performance, parasitic capacitance should be kept
to a minimum. Use of wire wound resistors should be avoided
because of their additional series inductance. Use of sockets
should also be avoided, if possible. Sockets add parasitic
inductance and capacitance that can result in compromised
performance. Minimizing parasitic capacitance at the amplifier's
inverting input pin is very important. The feedback resistor
should be placed very close to the inverting input pin. Strip line
design techniques are recommended for the signal traces.
As the signal is transmitted through a cable, the high frequency
signal will be attenuated. One way to compensate this loss is to
boost the high frequency gain at the receiver side.
