Notes
1. VDD2 is always equal VDD3.
2. Conditions are: VDD2 = 2.5 V, voltage multiplier = 3VDD2, bias system 1⁄6, VLCD output is loaded by 10 µA,
Tamb = 25 °C.
3. Valid for values of temperature, VPR and TC used at the calibration.
4. Conditions are: VDD1 = 1.8 V, VDD2 = 2.78 V, VLCD = 6.8 V, voltage multiplier = 3VDD2, bias system 1⁄6, inputs at VDD1
or VSS, serial interface inactive, internal VLCD generation, VLCD output is loaded by 10 µA; Tamb = 25 °C.
5. Conditions are: VDD1 = 1.8 V, VDD2 = 2.78 V, VLCD = 8.3 V, voltage multiplier = 4VDD2, bias system 1⁄7, inputs at VDD1
or VSS, serial interface inactive, internal VLCD generation, VLCD output is loaded by 10 µA; Tamb = 25 °C.
6. Load current 10 µA, outputs tested one at a time.
