PIN FUNCTIONS  
V+, V– (Pins 2, 7): Power Supply Pins. The V+ (Pin 2) and  
the V– (Pin 7) should be bypassed with a 0.1µF capacitor  
to an adequate analog ground. The filter’s power supplies  
should be isolated from other digital or high voltage  
analog supplies. A low noise linear supply is recom-  
mended. Using switching power supplies will lower the  
signal-to-noise ratio of the filter. Unlike previous mono-  
lithic filters, the power supplies can be applied at any  
order, that is, the positive supply can be applied before the  
negative supply and vice versa. Figure 2 shows the con-  
nection for dual supply operation.  
AGND (Pin 1): Analog Ground. The quality of the analog  
signal ground can affect the filter performance. For either  
single or dual supply operation, an analog ground plane  
surrounding the package is recommended. The analog  
ground plane should be connected to any digital ground at  
a single point. For dual supply operation Pin 1 should be  
connected to the analog ground plane.  
For single supply operation Pin 1 should be bypassed to the  
analog ground plane with a 0.47µF or larger capacitor. An  
internal resistive divider biases Pin 1 to 1/2 the total power  
supply. Pin 1 should be buffered if used to bias other ICs.
