Dual-Channel, I²C, 7-Bit Sink/Source
Current DAC
ABSOLUTE MAXIMUM RATINGS
Voltage Range on V_CC, SDA, and SCL
Relative to Ground.............................................-0.5V to +6.0V
Voltage Range on FS0, FS1, OUT0, OUT1
Relative to Ground..................................-0.5V to (V_CC + 0.5V)
(Not to exceed 6.0V.)
Operating Temperature Range ...........................-40°C to +85°C
Storage Temperature Range .............................-55°C to +125°C
Soldering Temperature ...............................Refer to the IPC/JEDEC
J-STD-020 Specification.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
