• RE: ADP151ACPZ-1.8 exposed pad connection in adjustable output voltage operation mode

    Hi Osipov-ae,

    Connect the EPAD to the PCB GND where the ADP151 GND pin is also connected.

    Best Regards,

  • Can AD820 "NC" be grounded?

    I'm using the AD820 in a loop filter in an RF circuit and I would like to maximize the ground plane area. Can the "NC" pins on the AD820 (SOIC-8) be grounded without ill effects? I am also using the ADP151 voltage regulator. Since the datasheet for the…

  • RE: 有奖“示爱”行动——谈谈那些让你爱爱爱爱不完的电路

    电源方面觉的最好用的,也是我用的最多的LDO就是ADP151,用了很多年从来没有出过一点问题,性价比太好,谁用谁知道。

  • RE: If I use Raspberry pi or Arduino instead Renesas Demonstration Kit (RDK) for RX62N, will it work for 12 lead application?

    Hello Anagha,

    As a minimum, you will need to provide supplies for AVDD and IOVDD. As you know ADCVDD and DVCC can be supplied from on chip regulators.

    The evaluation board was designed to operate primarily from a +5V incoming supply (to suit the wall…

  • RE: AD9912 power supply

    Saurabh,

    In general I would point you to the ADIsimPower tool for identifying your best options

    Here are a few options for you in the meantime:

    - For the 14.8V to 5V you can use the ADP2370 or the ADP2300 (1/2/3)

    - For the LDO from 5V to 3.3V we have…

  • RE: ADAS 1000 comunicates dut doesn't send digitized values

    Hello!

    I use two ADP151 3.3V for the IOVDD and AVDD, I think, they won't let any higher voltage on AVDD and IOVDD lines. The supply voltage for the two ADP151 is 5V from laptop USB. The STM32 board gets the same 5V and it has it's own 3V on board regulator…

  • Voltage Regulator for 16-bit ADC AD7626

    We are looking for an appropriate low-noise, low-drop voltage regulator to
    power the 16-bit ADC AD7626. Which device is a better fit : ADP3334 (5V, 2.5V)
    or ADP7104 (5V, 2.5V)? Is there any other voltage regulator that is more
    suitable…
  • Recommended regulators for ADI PLLs and VCOs

    PLL Recommended regulator
    Low power standalone PLLs and the ADF4360-x narrowband PLL/VCO family (< 100 mA); e.g. ADF41xx, ADF42xx, ADF4360-x

    Use the ADP150 regulator; good performance, low cost.

    Use…

  • 数模隔离咨询

    如上图所示的系统。

    现在转换板的Vcc_a和Vcc_b是一起的,用Vdd通过ADP151转换出来的3.0V,然后供给MCU的AD、各个放大器和后级传感器。现在发现,通过传感器引入的干扰会对这部分电源产生影响,所以想分开成如上图所示的两个Vcc。

    现在想咨询下,使用Vdd引出两路Vcc好,还是Vdd->Vcc_a->Vcc_b好,还是Vdd->Vcc_b->Vcc_a好?转换是用低噪声的LDO好还是基准电源好?各个电源模块的地通过什么连接好?

  • AD7746读出数据漂移

    由于项目需要,申请了AD7746样片。参考评估板搭建了测试电路,供电使用ADP151-3.3,电容传感器等电位驱动采用运放AD8656(AD2177也用过)。设置最慢的速度(最高精度)。

    采样1000多个点后用matlab稍微处理了下,数据一直很大幅度波动。Y轴表示的是读出数据转换成十进制的值,为了方便画图,跟研究震动情况,整体减掉了最少值。现在真心不解出了什么情况,为什么结果会是这样的,是我的AD7746芯片坏了吗?
