I need an information about ADM7151 ESD classification (or ESD HBM/CDM levels).
Can you help me?
I'm interested in your ADM7151 because of it's low noise and hi frequency PSSR, but I need a 2.0 amp output @7.8 volts. Is it possible to parallel devices to obtain higher output current? Any other suggestions on how to increase the output current…
I used ADM7151 for PLL+VCO power supply ,If the load 400mA current ，then the VCO output will uperimposed spur，if don't use ADM7151, the output is correct.，attachment are ADM7151 circuit diagrams and test phenomena ,so I want to know why ?
I'm using the ADM7151 to supply a PLL/VCO. It is to be supplied w/ 5V input and give 3.3V output. See my schematic below. However the output is actually going to ~4V @ Vin=4.5V, and 4.3V @ Vin=5V. It's also oscillating badly. I noticed that…
Cascading two ADM7151 will only preserve the output noise performance of the device. What the cascaded LDOs will improve is the PSRR performance.
I shifted the LO frequency around 470KHz, as below picture, the A-spur still existed and appeared another spur.
LDO we use ADM7151 and the capacitors are C0G type.
If we try to modify PCB layout, which traces should be taken care first??
The ADM7151 is connected correctly and you say you have a similarissue with the ADP125. I am thinking that there is another power sourcethat is pulling up the LDO outputs via the protection diodes or some otherleakage path in the loads. We need to see…
The reason why you are not seeing a hard short between VIN and EPAD is because the conductive material between the EPAD and substrate is not really low impedance. For proper operation of the ADP7182, the EPAD must be connected to VIN.
