AN-589: Ways to Optimize the Performance of a Difference Amplifier (pdf, 115 kB)
This Application Note presents several ways to build and optimize the performance of a discrete difference amplifier. It also recommends amplifiers that will make the overall solution cost/performance competitive with monolithic instrument amplifiers.
AN-584: Using the AD813X Differential Amplifier (pdf, 174 kB)
The AD813x differs from conventional op amps by the external presence of an additional input and output. The additional input, VOGM, controls the output common mode voltage.
