  • AD9042: Output drive of the VREF

    Q 

    We need to use the reference of the AD9042 to drive an external offset circuit.
    It would simplify the circuit if we can place a potential divider of say 10kR
    10kR to ground before the +ve input of the amplifier. The data sheet states the
    reference…

  • AD9027:  Do you have the detail circuit of dither generator using OP27 shown in AD9042 datasheet?

    Q 

    The following figure is from AD9042 datasheet. Do you have the detail circuit
    of OP27?

     

    A 

    The OP27 circuit we used is just as shown below except the resistor values are
    200 Ohms between pin 11 of the AD600 and pin 2 of the OP27.  The feedback

  • Sampling rate of AD9042, AD9254

    Hello!

    As per datasheet:

    AD9042: 41MSPS, 595mW

    AD9254: 150MSPS, 430mW

    If I use these ADCs at a lower sampling rate say 20MSPS (if its possible) will the ADC run at a reduced power? If so, what will be the power consumption in the case of reduced sampling…

  • Can I connect digital and analog supply of 3.3V in AD9042?

    Hello AD Experts,

    I am using AD9042 for Digital Control of Power Supply. 

    I am using FPGA as a digital controller which operates on 3.3V only. But here it is mentioned that the AD9042 requires 5V analog and digital power supply. 

    But absolute maximum…

  • RE: AD9042S的数字供电为5V，能不能与3.3V的FPGA直接相连？

    不建议直接连接使用。建议使用电平转换芯片进行处理，如ADI的ADG3300系列，或者其他厂家，如TI的SN74L系列电平转换器件。对于AD9042其实也可以考虑使用串联电阻的方式进行处理，但是要考虑因为电阻和分布电容带来的滤波效应，以免影响数字信号的正常传输。

  • AD9042供电求助

    想知道AD9042S的DVcc能否连接到3.3V，使其能够输出3.3V电平。

  • 大型强子对撞机再次“撞”出重大发现

    两年前的7月，欧洲核子研究中心宣布，通过大型强子对撞机底夸克实验（LHCb）发现了新粒子——五夸克粒子。此项研究由清华大学和美国雪城大学的研究人员，以及LHCb国际合作组成员共同完成。LHCb中国组负责人、清华大学高原宁教授说：“LHCb的实验，使人们相信自然界中除了常规物质，确实存在奇特态物质。”

    今天7月，LHCb 再次宣布发现了首个包含有两个重夸克的双粲重子 粒子，这是由LHCb 实验中国组科学家主导完成的重大研究成果。此次发现的 粒子由两个粲夸克和一个上夸克组成。由于粲夸克质量远大于上夸克…

  • High Speed ADC with Bipolar Analog Input

    Hello,

       I required an high speed ADC with bipolar analog input ranging from -V to +V. I was considering AD9042 but later on it came to my notice that it does not take in bipolar analog input. So, right now I am considering the following ADC's for the…

  • plutosdr : minimal tool chain for c compiling

    Hello,

    I’d like to use my C code with pluto to build a ‘’simple’’ stand alone receiver.

    I read a lot of Q&A and your answer here: https://ez.analog.com/university-program/f/q-a/104394/how-to-implement-c-code-examples…
