Converter Electrical Characteristics
Unless otherwise specified, the following specifications apply: AGND = DRGND = 0V, V_A = 3.3V, V_DR = +3.0V, Internal V_REF =
+1.2V, f_CLK = 105 MHz, V_CM = V_CMO, C_L = 5 pF/pin. Typical values are for T_A = 25°C. Boldface limits apply for T_MIN ≤ T_A ≤
T_MAX. All other limits apply for T_A = 25°C (Notes 8, 9)
