1. The AAT3152 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. Current matching is defined as the deviation of any sink current at IOUT = 20mA and 2mA.
3. Specification applies only to the tri-mode charge pump.
