At –40°C to 85°C, V_ref [REF+ – (REF–)] = 5 V when +VA = +VBD = 5 V or V_ref [REF+ – (REF–)] = 2.5 V when
+VA = +VBD = 3 V, f_SCLK = 42 MHz, or V_ref = 2.5 when +VA = +VBD = 2.7 V, f_SCLK = 37.8 MHz, f_i = DC for DC
curves, f_i = 100 kHz for AC curves with 5-V supply and f_i = 10 kHz for AC curves with 3-V supply (unless
otherwise noted)
