• RE: Asking about supply voltage Type for AD8672


    The amplifier doesn't have GND pin, only V- and V+ which is your connection for high and low potentials.
    The part's performance is specified to +/-5V and +/-15V or that is 10V and 30V while your Abs Max is up to 36V.

    Thanks and regards!

  • Indirect feedback noise simulation with LT1167 and AD8672

    Hello friends,

    I wish to do a noise simulation on a current source controller using the LT1167 instrumentation amplifier and the AD8672 low noise op-amp. what is the correct approach for noise simulation on a indirect feedback circuit like this? In LTspice…

  • Loading between channels on AD8672?

    Im using the AD8672 on the dual op amp evaluation board to provide 2 output channels.

    Both amplifier A and B are given the same 30us input signal. Amplifier A is behaves normally as long as Amplifier B is not connected to a scope (50ohm termination)…

    想請問一下我使用AD8672 spice model  去跑Open-Loop Gain and Phase Shift vs. Frequency &  Output Impedance vs. Frequency  這兩個參數,RUN出來的參數為何 DATASHEET上面所標示的是不一樣的,測試條件與Datasheet一樣 , 詳細測試數據在附件,thanks!!!

  • Replacement for AD8672

    Hi all!!

    for building a precise and efficient Sample and Hold circuit, i found the following application note in AD website

  • RE: Form, Fit and Functional replacement for OP227AY/883


    The suggested replacement part for the OP227 is AD8672-EP.
    This part is a Precision, Low Noise, Low Input Bias Current Op Amp and also specified over -55 to 125'C temperature range.
    However, this is available in 8-lead SOIC_N only.

    Can you check…
