VREF is used to provide charging current to the oscillator timing capacitor through the timing resistor. It is important for reference stability that VREF is bypassed to GROUND with a ceramic capacitor connected as close to the pin as possible. A minimum value of 0.1-µF ceramic is required. Additional VREF bypassing is required for external loads on VREF. |
