I
SMAX
= Maximum quiescent supply current
V
OUT
= Maximum output voltage of the application
R
LOAD
= Load resistance tied to ground

LOAD
= Load current
N = number of amplifiers (max = 2)
By setting the two PD

equations equal to each other, we
can solve the output current and R
LOAD
to avoid the device
overheat.
Power Supply Bypassing 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 short as possible. The power supply
pin must be well bypassed to reduce the risk of oscillation.
For normal single supply operation, where the V
S
- pin is
connected to the ground plane, a single 4.7μF tantalum
capacitor in parallel with a 0.1μF ceramic capacitor from V
S
+
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 V
S
- pin becomes the negative
supply rail.
Printed Circuit Board Layout
For good AC performance, parasitic capacitance should be
kept to 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.
Application Circuits
Sullen Key Low Pass Filter
A common and easy to implement filter taking advantage of
the wide bandwidth, low offset and low power demands of
the ISL55002 and ISL55004. A derivation of the transfer
function is provided for convenience (See Figure 28).
Sullen Key High Pass Filter
Again this useful filter benefits from the characteristics of the
ISL55002 and ISL55004. The transfer function is very similar
to the low pass so only the results are presented (See Figure
29).
