1. According to the data sheet for the ADR366A or (B) page 1 and under Features: No External Capacitors Required. In Page 17, Applications (Basic Voltage Reference Connection): “However, a 0.1 μF ceramic output capacitor is recommended to absorb and deliver the charge as is required by a dynamic load”. Hmmmm..? Any limits for the “charge”?2. What happens if we don’t use the capacitors? Witch is one is important, the input or output?
Answer 1) there is no limit on the charge, but limiting factor is the settling time of the Device – just take care not to exceed this. ( If you do, this may cause a saw-tooth waveform at the output. )Answer 2). The input is not important, for a dynamic load the output one may be required, but this will only depend on your application tests. It is quite possible the output capacitor may not be needed at all.
