GND will disable the amplifier. The amplifier will be enabled
when the signal at ENABLE pin is 2V above GND.
Output Drive Capability
The maximum output current for the ISL59831 is set at
±50mA. Maximum reliability is maintained if the output
current never exceeds ±50mA, after which the electro-
migration limit of the process will be exceeded and the part
will be damaged. This limit is set by the design of the internal
metal interconnections.
Power Dissipation
With the high output drive capability of the ISL59831, it is
possible to exceed the +150°C absolute maximum junction
temperature under certain load current conditions.
Therefore, it is important to calculate the maximum junction
temperature for an application to determine if load conditions
or package types need to be modified to assure operation of
the amplifier in a safe operating area.
The maximum power dissipation allowed in a package is
determined according to Equation 1:
Where:
T
JMAX
= Maximum junction temperature
T
AMAX
= Maximum ambient temperature
Θ
JA
= Thermal resistance of the package
The maximum power dissipation actually produced by an IC
is the total quiescent supply current times the total power
supply voltage, plus the power in the IC due to the load, or:
for sourcing:
for sinking:
Where:
V
S
= Supply voltage
I
SMAX
= Maximum quiescent supply current
V
OUT
= Maximum output voltage of the application
R
LOAD
= Load resistance tied to ground
I
LOAD
= Load current
i = Number of output channels
By setting the two P
DMAX
equations equal to each other, we
can solve the output current and R
LOAD
to avoid the device
overheat.
Power Supply Bypassing and Printed Circuit
Board Layout
Strip line design techniques are recommended for the input
and output signal traces. As with any high frequency device,
a good printed circuit board layout is necessary for optimum
performance. Lead lengths should be as short as possible.
The power supply pin must be well bypassed to reduce the
risk of oscillation. For normal single supply operation, a
single 4.7μF tantalum capacitor in parallel with a 0.1μF
ceramic capacitor from V
CC
and V
CP
to GND will suffice.
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 can result in
compromised performance. Minimizing parasitic capacitance
at the amplifier's inverting input pin is also very important.
