Configurable, Isolated 10-bit ADCs for
Multi-Range Binary Inputs
Electrical Characteristics (continued)
(V_DDL - V_GNDL = 1.71V to 5.5V, V_DD - V_GNDL = 3.0V to 3.6V, R_ISET = 120kΩ, T_A = -40°C to +125°C, V_GNDF = V_GNDL. Typical values
are at T_A = +25°C with V_DDL = V_DD = +3.3V, R_ISET = 120kΩ, V_GNDF = V_GNDL.) (Notes 2, 3)
