APPLICATION INFORMATION
power supply restrictions
Although the THS6007 is specified for operation from power supplies of
±
5 V to
±
15 V (or singled-ended power
supply operation from 10 V to 30 V), and each amplifier has its own power supply pins, several precautions must
be taken to assure proper operation.
1.
The power supplies for each driver amplifier must be the same value. For example, if driver 1 uses
±
15 volts,
then driver 2 must also use
±
15 volts. Using
±
15 volts for driver 1 and
±
5 volts for driver 2 is not allowed.
2.
The power supplies for the receiver amplifiers may be different than the driver supply voltages. Although
it is recommended to use the same type of supply, either split supplies(
±
V
CC
) or single supply (+V
CC
and
GND), for both drivers and receivers.
All the amplifiers within the THS6007 incorporate a standard Class A-B output stage. This means that some
of the quiescent current is directed to the load as the load current increases. So under heavy load conditions,
accurate power dissipation calculations are best achieved through actual measurements. For small loads,
however, internal power dissipation for each amplifier in the THS6007 can be approximated by the following
formula:
PD
2 VCCICC
VCC_ VO
VO
RL
Where:
P
D
V
CC
= Split supply voltage
I
CC
= Supply current for that particular amplifier
V
O
= Output voltage of amplifier
R
L
= Load resistance
= Power dissipation for one amplifier
To find the total THS6007 power dissipation, we simply sum up all four amplifier power dissipation results.
Generally, the worst case power dissipation occurs when the output voltage is one-half the V
CC
voltage. One
last note, which is often overlooked: the feedback resistor (R
f
) is also a load to the output of the amplifier and
should be taken into account for low value feedback resistors.
