Typ. Max. Unit Supply Voltage1,2 VCC Operating, TJ ≤ 165 °C 3.0 – 24 V Supply Current ICC(L) A1150, A1157 B > BOP 2.0 – 5.0 mA A1158 B < BRP A1152, A1155 B > BOP 5 – 6.9 mA A1153, A1156 B < BRP ICC(H) A1150, A1152, A1155, A1157 B < BRP 12 – 17 mA A1153, A1156, A1158 B > BOP Supply Zener Clamp Voltage VZ(sup) ICC(L)(max) + 3 mA, TA = 25°C 28 – – V Supply Zener Clamp Current IZ(sup) VZ(sup) = 28 V – – ICC(L)(max) + 3 mA mA Reverse Supply Current IRCC VRCC = –18 V – – –1.6 mA Output Slew Rate3 di/dt No bypass capacitor, capacitance of probe CS = 20 pF –90– mA/ μs Chopping Frequency fc – 700 – kHz Power-Up Time4,5 ton A1150, A1152, A1155, A1157 B > BOP + 10 G –– 25 μs A1153, A1156, A1158 B < BRP – 10 G Power-Up State2,4,6,7 POS ton < ton(max), VCC slew rate > 25 mV/μs– ICC(H) –– 1VCC represents the generated voltage between the VCC pin and the GND pin. 2The VCC slew rate must exceed 600 mV/ms from 0 to 3 V. A slower slew rate through this range can affect device performance. 3Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change. 4Power-Up Time is measured without and with bypass capacitor of 0.01 μF. Adding a larger bypass capacitor would cause longer Power-Up Time. 5Guaranteed by characterization and design. 6Power-Up State as defined is true only with a VCC slew rate of 25 mV/μs or greater. 7For t > ton and BRP < B < BOP, Power-Up State is not defined.
