PIN FUNCTIONS

resistors, R

V
for the 2nd Filter Stage. Its value programs the common
mode voltage of the differential output of the fi lter. Pin 2 is a
high impedance input, which can be driven from an external
voltage reference, or Pin 2 can be tied to Pin 7 on the PC
board. Pin 2 should be bypassed with a 0.01μF ceramic
capacitor unless it is connected to a ground plane.
V
3.3V or 5V supply (Pin 6 grounded) a quality 0.1μF ceramic
bypass capacitor is required from the positive supply pin
(Pin 3) to the negative supply pin (Pin 6). The bypass
should be as close as possible to the IC. For dual supply

ceramic capacitor to Pin 6. For dual supply operation,
Pin 7 can be bypassed or connected to a high quality DC
ground. A ground plane should be used. A poor ground
will increase noise and distortion. Pin 7 sets the output
common mode voltage of the 1st stage of the fi lter. It has
a 5.5kΩ impedance, and it can be overridden with an
external low impedance voltage source.
