enabled, outputs disabled

Temperature range: −40°C to +105°C; typical at +25°C.

Guaranteed by design and characterization; not production tested.

For current outputs with internal RSET, the offset, full-scale, and TUE measurements exclude dc crosstalk. The measurements are made with all four channels enabled

and loaded with the same code.

See the Current Output Mode with Internal RSET section for more information about dc crosstalk.

Efficiency plots in Figure 32 through Figure 35 include the IBOOST quiescent current.
