NOTES

∆CMRR is 20 log10 VCM/∆CME, where VCM is the voltage applied to both noninverting inputs and ∆CME is the difference in common-mode input-referred error.

∆PSRR is: Input-Referred Differential Error

NOTE

Electrical tests are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteed

for standard product dice. Consult factory to negotiate specifications based on dice lot qualification through sample lot assembly and testing.
