1Temperature range: −40°C to +105°C; typical at +25°C.

2 Guaranteed by design and characterization; not production tested.

3 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

loaded with the same code.

4 See the Current Output Mode with Internal RSET section for more explanation of the dc crosstalk.

5 Efficiency plots in Figure 54, Figure 55, Figure 56, and Figure 57 include the IBOOST quiescent current.
