just a minor one. On page 14, Fig 41 you have got positive feedback.
可以接地，可以考虑使用一下AD8270， AD8278，但是温度范围达不到 125C
AD628 AD8279 AD8278 AD8271 AD8274 AD8273 AD8270
I found that the proposed scheme is well known as the Howland Current SourceAs a current source it has such drawbacks as low output current and need in well matched resistors.But it is enough for ADAU1701's ADCs which sink 100uA .And moreover, Analog…
采用 分压电阻 加 运放 可以实现衰减，Kohm级电阻 会造成 万分之一 二 的误差，可以满足 12bit精度
也可以采用 0.5 倍增益的 差动运放， AD8270/71/73/74/78/79 , 同时将 Vref设置为5V
VDD的电压的正常范围2.7~5.5V，最大不能超过7V, 如果Vin施加 10Ｖ电压 将可能损坏芯片
Hi F. Buonomo,
Please check this great article for the different current sense topologies and some information on the consideration and how to use them. I think the one shown on Figure 1 d is a good approach.
With regards to the parts, please have a look…
Hi Analog! I want to sum 4 channel output of ADA8282 "Radar receiver Path AFE: 4-Channel LNA PGA"
by op-amps and feed them to ARM cotrex-M7 microcontroller. though these channel are differential I want the final one as single ended, assume…
I talked to an in amp designer about this question. He mentioned that it might be possible that the short circuit current limit is engaging, although he would be surprised. The short circuit current limit is something we spec as a typical number…
