Due to the low operating frequency, the gate time must be 100ms to ensure an accurate frequency measurement. 2. Stability is specified for two operating voltage ranges. Stability progressively degrades with supply voltage below 1.5V. Measured peak-to-peak. Inclusive of initial tolerance at +25C, and variations over operating temperature, rated power supply voltage and load. 3. Core operating current does not include output driver operating current or load current. To derive total operating current (no load), add core operating current + output driver operating current, where output driver operating current = C *V *F . driver out out 4.
