• ADL5569 maximum PDB / PDB2 current when driven low

    Hello.

    Could Analog let me know what the maximum current out of PDB/PDB2 is when the PDB/PDB2 pin is driven to 0V?

    The datasheet states a typical value of -70uA, but does not give a worst case.

    I would like to calculate the largest series resistance I…

  • Phase noise of ADL5569 or other fast differential amplifiers

    I am going to use the most resent and the fastest ADL5569 differential amplifier as a buffer at the output of DDS. Naturally my aim is to impose as lower as possible phase noise on the DDS output signal. But the ADL5569 datasheet does not contain any…

  • What's the real absoluted max Supply Voltage for ADL5569?

    Good Morning, 

    I have a question about the maximum allowed value of Supply Voltage for the component ADL5569. In the datasheet, the absolute Supply value indicated is 5.25V. But subsequently in the field "interface Port" I can read the same value (5.25V)…

  • ADL5569 with single end input and differential output to AD6674

    I'm designing an ADC circuit with 0-100Mhz single end input. suppose to use ADL5569 as input amplifier, which also convert the single end input to differential. as the DC signal have to be sampled, so the whole circuit is DC coupled.

    The AD6674 require…

  • Residual phase noise of ADL5569 or any other fast differential amplifier

    I am going to use the most resent and the fastest ADL5569 differential amplifier as a buffer at the output of DDS. Naturally my aim is to impose as lower as possible phase noise on the DDS output signal. But the ADL5569 datasheet does not contain any…

  • ADL5569 Dual Differential Driver Amp - question about the enable inputs

    Can PDB and PDB2 be tied together without loss in amp-to-amp isolation? Are these truly digital inputs? I want to run these enable pins off of the 5V I'm using for powering the chip. I will use a voltage divider with a 10K from 5V to these pins and a…

  • RE: ADL5565 linearity up to 4GHz

    Hi Victor,

    I would recommend the ADL5569. This part is not released yet, but will soon. The prelim datasheet can be found at the following link below.

    Hope this helps.

  • RE: Questions about dc-coupled application of AD9208

    1. the input common mode (at VINA+/- or VINB+/-) voltage will change based on the buffer current setting. It can change from a typical of 1.32V to around 1.52V. If using the export VCM feature, please follow the instructions as described in the datasheet…

  • RE: ADL5567 VCOM circuit

    There is a nontrivial internal circuit that sets the common-mode, which can be thought of as a resistive voltage divider with a few kOhm for the sake of this explanation. Unfortunately, it can not be assumed high-Z, and in practice it is not just a simple…

  • ADL5565 S-Parameters higher than 3GHz?

    Dear all,

    we are currently using the ADL5565 as a balun alternative from DC to 3GHz and would like to exand it to 6GHz or higher. Unfortunately, the provided S-Parameters file ends at 3GHz and looks somehow weird:

    Thus, either the stated input resistance…
