BLOCK DIAGRAM
+OUTA, – OUTA (Pins 27, 29): Output Pins. Pins 27 and
29 are the lter differential outputs for channel A. With a
typical short-circuit current limit greater than ±40mA, each
pin can drive a 100Ω and/or 50pF load to AC ground.
VMIDA (Pin 34): The VMIDA pin is internally biased at mid
supply, see Block Diagram. For single supply operation
the VMIDA pin should be bypassed with a quality 0.01μF
ceramic capacitor to Pins V–. For dual supply operation,
Pin 34 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 34 sets the output
common mode voltage of the 1st stage of the lter in chan-
nel A. It has a 5.5kΩ impedance, and it can be overridden
with an external low impedance voltage source.
Exposed Pad (Pin 35): V–. The Exposed Pad must be
soldered to PCB. If V– is separate from ground, tie the
Exposed Pad to V–.
