ADM7154, ADM7155: Are there any other design considerations for low noise?

Q
ADM7154, ADM7155: Are there any other design considerations for low noise?

A
The ADM7154/ADM7155 architecture means that the output noise does not scale
with voltage for the fixed output voltage models. A simple RC network can be
added…

Recommended PCB layout for ADM7154/55 SOIC looks odd

ScottB

On page 22 of the datasheet there are PCB layout recommendations. For the SOIC package the ground pour is shown as discontinuous between the thermal pad and the input capacitor. The attached image shows what I'm talking about; C1 is the input cap. …

Does the output noise of the ADM7154/ADM7155 scale with the output voltage?

Q
Does the output noise of the ADM7154/ADM7155 scale with the output voltage?

A
Unlike the majority of low noise LDOs where the output noise increases with the
output voltage, the unique architecture of the ADM7154/ADM7155 keeps
the output…

RE: ADRV9009 FMC board - would using an ultra low noise LDO on the VCXO supply input improve performance?

PVALAVAN

You can consider deriving supply for AD9528 and VCXO from ADM7154 LDO.

Input to ADM7154 can be from ADP5054.

RE: similar part to the ADI7150 but lower input voltage

hyao

Hi Belenie,

Do you mean the similar part to the ultralow noise LDO ADM7150 that takes lower input voltage?

The ADM7154/5 are the ultralow noise LDOs that take 2.3-5.5V input voltage.

RE: LDO for RF LNA

Errgy
Hi,

For RF applications, I suggest you use ADM715x/ADP715x RF LDOs with high PSRR and ultralow noise performance. ADM7154 is a recommended LDO for your application with the following characteristic performance:
- PSRR:
  
  90 dB (200 Hz to 200 kHz);
  
  58 dB…

Hi Chris,

Yes, this is a 3.3V model option. The last 2 digits of the top most marking shows the model option for the ADM7154 SOIC package.

RE: ADP150 and capacitor choise

Jason_Duan

The sch looks good! If your application needs high performance of noise level, ADI also has ADM7154, which RMS noise is only 1.6uVrms compared to 9uVrms of ADP151. Thank you.

RE: 300mA 9uV noise LDO

AIlustrisimo

Hi Jaana_jia,

You may use ADM7154, features are as follows:

VIN range: 2.3V to 5.5V
Maximum output current: 600mA

Low Noise:
0.9 µV rms total integrated noise from 100 Hz to 100 kHz
1.6 µV rms total integrated noise from 10 Hz to 100 kHz

Regarding LDO current rating in adrv9009-zu11eg evaluation board schematic

Sid@123

Hi Team ADI,

We are designing a modem taking adrv9009-zu11eg as reference.

I have one doubt with respect to 1.8V supply for ADRV9009.

As per datasheet,

VDDA1P8_TX Supply(ORX ENABLED) :455 mA (Transmitter RF attenuation = 0 dB, full scale CW)
