Recently I purchased a reference module with AD584J from Aliexpress. 2.5 V, 5 V, 7.5 V work perfectly, but 10 V behaves strangely. If I set the jumper to 2.5 V, then switch it immediately to 10 V, the output voltage drops down to 2.1..2.2 V, then slowly (within 10..30 seconds) crawls up to 4..5 V and then jumps to 10.00 V (screenshot 1, 5 s/div!).
To get 10 V instantly, I need to set 5 V (or 7.5 V), then switch to 10 V (screenshot 2, also 5 s/div). Is it normal for this chip? The module is powered off a 12 V 0.25 A transformer (not switching) power supply.
