I am trying to use ADM8828 to provide -5V rail.
-5V is output under open circuit, no load conditions.
But with any load connected the output voltage slumps, e.g. -0.5V across 270 Ohm.
ADM8828 datasheet RevA p 2 recommends electrolytic charge pump capacitors…
symbols used in exemplary circuit of the datasheets shows use of polar capacitors, would it be okay if I use non polar capacitors? I'm trying to use non polar ceramic capacitors due to low noise and current leakage. Would it still work without affecting…
I would like to use the ADM8828 but I can't find information on the state of the output when the IC is in shutdown.
Is there any information available for this?
Now I am developing the PCB with ADM8829 part.
Does the ADM8829 NC pin have any internal connection?
I would like to connect this pin to GND and make the PCB apply as for ADM8828 as for ADM8829 part.
Attached is the application circuit to bias HMC460 with HMC920.
The application note, AN-1363 also has some example circuits. And the formulas required to calculate the external component values. If you can share your apps circuit for HMC8410, we…
