Note 1 The 21 41 and 43 devices are connected for unity-gain operation with 75X load and an input span of g1V The 22 42

and 44 devices are connected for a gain of a2 with a 150X load and a g1V input span with RF RG 270X

Note 2 The 21 and 41 devices are connected for unity gain with a g3V input span while the output swing is measured

Note 3 CMIR is assured by passing the CMRR test at input voltage extremes
