APPLICATIONS INFORMATION  
Tips for Best Differential Output Performance  
DIFFERENTIAL DRIVE  
For best ac performance, an op amp with at least 2 MHz gain  
bandwidth and 1 ꢀ/μs slew rate is recommended. Good choices  
for op amps are the AD8641, AD8515, or AD820.  
Figure 64 shows how to configure the AD8227 for differential  
output.  
+IN  
Keep trace lengths from resistors to the inverting terminal of  
the op amp as short as possible. Excessive capacitance at this  
node can cause the circuit to be unstable. If capacitance cannot  
be avoided, use lower value resistors.

PRECISION STRAIN GAGE  
OP AMP  
The low offset and high CMRR over frequency of the AD8227  
make it an excellent choice for bridge measurements. The  
bridge can be connected directly to the inputs of the amplifier  
ꢁsee Figure 65).  
–OUT  
RECOMMENDED OP AMPS: AD8515, AD8641, AD820.

The advantage of this circuit is that the dc differential accuracy  
depends on the AD8227 and not on the op amp or the resistors.  
This circuit takes advantage of the AD8227s precise control of  
its output voltage relative to the reference voltage. Op amp dc  
performance and resistor matching affect the dc common-mode  
output accuracy. However, because common-mode errors are  
likely to be rejected by the next device in the signal chain, these  
errors typically have little effect on overall system accuracy.
