__________Applications Information
Input Bypassing
For the best line-transient performance, decouple the
input with a 0.1µF ceramic capacitor as shown in the
Typical Operating Circuit. Locate the capacitor as
close to the device pin as possible. Where transient
performance is less important, no capacitor is neces-
sary.
Output Bypass
The MAX6120 performs well without an output decou-
pling capacitor. If your application requires an output
charge reservoir (e.g., to decouple the reference from
the input of a DAC), then make sure that the total output
capacitive load does not exceed 10nF.
