BIPOLAR OPERATION  
LAYOUT CONSIDERATIONS  
The connections for bipolar ranges are shown in Figure 4. Again,  
as for the unipolar ranges, if the offset and gain specifications  
are sufficient, the 100 W trimmer shown can be replaced by a  
50 W ± 1% fixed resistor. The analog input is applied as for the  
unipolar ranges. Bipolar calibration is similar to unipolar calibra-  
tion. First, a signal 1/2 LSB above negative full scale is applied,  
and R1 is trimmed to give the first transition (0000 0000 0000  
to 0000 0000 0001). A signal 1 1/2 LSB below positive full  
scale is applied and R2 trimmed to give the last transition  
(1111 1111 1110 to 1111 1111 1111).  
Many data acquisition components have two or more ground pins  
that are not connected together within the device. These grounds  
are usually referred to as the Logic Power Return, Analog Com-  
mon (Analog Power Return), and Analog Signal Ground. These  
grounds must be tied together at one point, usually at the system  
power supply ground. Ideally, a single solid ground would be  
desirable. However, since current flows through the ground  
wires and etch stripes of the circuit cards, and since these paths  
have resistance and inductance, hundreds of millivolts can be  
generated between the system ground point and the ground pin  
of the AD578 or AD579. Separate ground returns should be  
provided to minimize the current flow in the path from sensitive  
points to the system ground point. In this way supply currents  
and logic-gate return currents are not summed into the same  
return path as analog signals, where they would cause measure-  
ment errors.

6.8F  
Each of the AD578 or AD579 supply terminals should be capaci-  
tively decoupled as close to the ADC as possible. A large value  
capacitor such as 10 mF in parallel with a 0.1 mF capacitor is  
usually sufficient. Analog supplies are bypassed to the Analog  
Power Return pin and the logic supply is bypassed to the Digital  
GND pin.

Figure 4. Bipolar Input Connections  
To minimize noise, the reference output (Pin 24) should be  
decoupled by a 6.8 mF capacitor to Pin 30.
