Electrical Characteristics
C
Typical values are T
1. The AAT3152 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured
2. Current matching is defined as the deviation of any sink current at I
3. Specification applies only to the tri-mode charge pump.
