• AD8605 performances at -55°C

    Hi,

    I am using this amplifier to create constant current source by driving a MOSFET.

    The package is SOT-23.

    The amplifier is 5V-supplied.

    I know that operationnal range of AD8605 is -40°C/+125°C but I plan to use this op amp at -55°C, and I don't…

    需要利用AD8605在protelDXP搭建模型,并且建立相应的PCB板图,但是protelDXP中没有AD8605的模型,如何获得可以运用于protelDXP的模型,即元件。

  • MAX4475 alternative

    At the moment we are using an opamp from Maxim for all our amplifier design
    (MAX4475). But the MAX4475 is not an input rail-to-rail opamp so we are
    searching for a new opamp for our futures designs.

    What we need is a low noise, low…

  • RE: Unstable, voltage reference of AD7682/AD7689

    Hello Richie,

    now you are using AD8605 opamp, which can, according to the datasheet, handle the 4.096V input voltage.

    I am curious if you are still observing problems.

    Regards,

    Reinhard

  • RE: Question on using internal reference of AD7682

    Hi, Richie.

    The bandgap voltage is stable. And as you have noted, it can be used as a source with a suitable buffer such as the AD8605 and AD8031 since the current output of REFIN is limited.

    Regards,

    Karen

  • RE: about AC and DC measurements with ADuCM350

    Hi,

    Unfortunately not. We have not validated this on the bench to date so you will need to test it out using the evaluation board - altho we have used the AD8605 in a similar application in the loop and it worked well.

  • AD8605 schematic with ICS-40300 questions?

    Dear All,

    The project is for acquiring heart sound device with MCU ADC. The input frequency range are from 20Hz to 2KHz.

    For lower frequency performance, a high SPL analog microphone is selected. We also saw some documents about microphone preamp circuit…

  • About AD8605 Offset Voltage Temperature dependence Condition

    I have Qustion about AD8605 Offset Voltage Temperature dependence Condition.

    The detasheet P4 say 

    Offset Voltage
    VOS : −40°C < TA < +125°C MAX 750 μV

    The condition is only Vcm=Vs/2 or Vcm 0 to 5V ?
