ABSOLUTE MAXIMUM RATINGS
Characteristics Supply Voltage Analog Output Voltage Digital Input Voltage Reference Voltage Operating Temperature Range Symbol VDD (VDD18A1,VDD18A2) VOUT D[9:0] VRT VRB Topr Value 3.3 VSS18A1 to VDD18A1 VSS18A2 to VDD18A2 VDD18A1 VSS18A2 0 to 70 °C Unit V V V V
NOTES: 1. ABSOLUTE MAXIMUM RATING specifies the values beyond which the device may be damaged permanently. Exposure to ABSOLUTE MAXIMUM RATING conditions for extended periods may affect reliability. Each condition value is applied with the other values kept within the following operating conditions and function operation under any of these conditions is not implied. 2. All voltages are measured with respect to VSS(VSS18A1 or VSS18A2 or VBBA) unless otherwise specified. 3. 100pF capacitor is discharged through a 1.5k resistor (Human body model)
