+OUTA, – OUTA (Pins 27, 29): Output Pins. Pins 27 and
29 are the fi lter differential outputs for channel A. With a
typical short-circuit current greater than ±40mA, each pin
can drive a 100Ω and/or 50pF load to AC ground.

will increase noise and distortion. Pin 34 sets the output
common mode voltage of the 1st stage of the fi lter in chan-

with an external low impedance voltage source.
