TYPICAL PERFOR
PI FU CTIO S
LTC1164-6
NC (Pins 1, 8, 13): Pins 1, 8, and 13 are not connected to
any internal circuit point on the device and should prefer-
ably be tied to analog ground.
V
a 50k resistor tied to the inverting input of an op amp.
GND (Pins 3, 5): The filter performance depends on the
quality of the analog signal ground. For either dual or
single supply operation, an analog ground plane sur-
rounding the package is recommended. The analog ground
plane should be connected to any digital ground at a single
point. For dual supply operation, Pins 3 and 5 should be
connected to the analog ground plane. For single supply
operation Pins 3 and 5 should be biased at 1/2 supply and
they should be bypassed to the analog ground plane with

ground. The filter’s power supplies should be isolated
from other digital or high voltage analog supplies. A low
noise linear supply is recommended. Using a switching
power supply will lower the signal-to-noise ratio of the
filter. The supply during power-up should have a slew rate
less than 1V/µs. When V
