CONVERTER CHARACTERISTICS
ABSOLUTE MAXIMUM RATINGS
Supply Voltage (VDD).................................. –0.3V to 4V
Digital Output Ground Voltage (OGND)....... –0.3V to 1V
Analog Input Voltage (Note 3) .....–0.3V to (VDD + 0.3V)
Digital Input Voltage ....................–0.3V to (VDD + 0.3V)
Digital Output Voltage............... –0.3V to (OVDD + 0.3V)
Power Dissipation............................................2000mW
Operating Temperature Range
LTC2205-14C .......................................... 0°C to 70°C
LTC2205-14I ....................................... –40°C to 85°C
