Q
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?
A
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.
