T Same specification as for DAC7621E.

NOTES: (1) This term is sometimes referred to as Linearity Error or Integral Nonlinearity (INL). (2) Specification does not apply to negative-going transitions where

the final output voltage will be within 3 LSBs of ground. In this region, settling time may be double the value indicated.
