Table 6. Voltage Converter Specifications
1.9 ≤ V_DD ≤ 3.6 V; TA = –40 to +85 °C (G grade) or –40 to +125 °C (Y grade); default conversion time, V_REF = 1.25 V internal or
V_DDA, buffered and unbuffered mode, unless otherwise noted.

∆G
V_REF = 1.25 V; gain is absolute
—
V_REF = V_DD; gain is relative to V_DD —
Notes:
1. In unbuffered mode, R_IN*C_IN should be < 0.5usec. C_IN minimum is around 10 pF.
2. In buffered mode, VINP and VINN must be > 0.5 V and < V_DD for best performance.
