The AAT2806 is guaranteed to meet performance specifications over the -40°C to 85°C operating temperature range and is assured by design, characterization, and correlation with statistical process controls. 2. Specification applies only to the tri-mode charge pump. 3. Specification applies only to the charge pump doubler. 4. Determined by the sum of all active channels 5. Current matching is defined as the deviation of any sink current at I OUT = 20mA and 2mA. |
