142 / 157 page  ST7LITE1xB 142/157 13.12 ANALOG COMPARATOR CHARACTERISTICS 13.13 PROGRAMMABLE INTERNAL VOLTAGE REFERENCE CHARACTERISTICS 13.14 CURRENT BIAS CHARACTERISTICS (for Comparator and Internal Voltage Reference) Notes: 1. Unless otherwise specified, typical data are based on TA=25°C and VDD-VSS=5V. They are given only as design guide- lines and are not tested. 2. Since startup time for internal voltage reference and bias is 1 µs, comparator correct output should not be expected before 1 µs during startup.
