VREFDDR specifications
Table 20. VREFDDR electrical characteristics
Consumer T_A = -40 to 85 °C and Extended Industrial T_A = -40 to 105 °C, V_IN = 3.6 V, I_REFDDR = 0.0 mA, V_INREFDDR = 1.5 V and typical
external component values, unless otherwise noted. Typical values are characterized at V_IN = 3.6 V, I_REFDDR = 0.0 mA, V_INREFDDR =
1.5 V, and 25 °C, unless otherwise noted.
