Is there any instrumentation amplifier which has same spec or better to AD624 (mil grade) but with SMT packaging?
hi.. I am designing programmable gain low noise amplifier by using AD624 with AD7528 and AD712 . Can you please help me out with circuit operation and how can i change my gain using digital data.
Hello,
I am designing an op amp circuit and would like to use either the AD524 (cheaper, available in surface mount package) or the AD624 ("newer" part number, but more expensive, not available in surface mount package).
Since both op amps…
Hello, my name is Eduardo Heredia and I am a student of Electronics Engineering at the National University of San Luis (Argentina). I am doing my final project; this is a digitally programmable signal conditioner from a plate with FPGA. The signal co…
Hi all,
We are using AD624 Instrumentation Amplifier for our signal Conditioning Application for Strain gauge based sensor like Force and Torque Sensors. Here we get Voltage in mV and we are using AD624 as IA and then a second order Butter worth filter…
使用624放大器时，设置500倍，使用程控电源同时给16路放大器输入10mv，输出仅4伏，跟通道数量有相关，连接传感器，放大正常，可能会是什么原因？非常着急，非常感谢来电致李正兵13571910691
Hello Expert,
how to choose auxiliary op amp for testing AD624? is there any general rule for selection?
I found the Simple Op Amp Measurements method from ADI website.

AD624是20年前的产品，性价比很低。建议看下AD8422，是ADI第三代的AD620.
Hi Jason,
AD524 and AD624 might not be the suitable amplifiers for your application. The AD524 arequires an input bias current of 25 nA - 50 nA while the AD624 requires an input bias current of 15nA - 50 nA depending on the grade of the part, the amplifiers…
