NOTES:
1. Parameter guaranteed by design or characterization and not production tested.
2.
θ
JA
is measured with the component mounted on an evaluation PC board in free air.
3. Gain Error measured as the error in the ratio between the full scale output current and the current through R
SET
(typically 625
μ
A). Ideally the
ratio should be 32.
4. See ‘Definition of DAC Specifications’ section.
