Specification same as INA2128P, U.
NOTE: (1) Input common-mode range varies with output voltage—see typical curves. (2) Guaranteed by wafer test. (3) Temperature coefficient of the “50k
” term in
the gain equation. (4) Nonlinearity measurements in G = 1000 are dominated by noise. Typical nonlinearity is
±
0.001%.
