Dear Team,
I would like to know more about the attached circuit Please share your thoughts.
In this circuit, the output of ADR440 is filtered first using an active LPF and then using a passive LPF.
The output of the 2nd filter is going to the I/P of an…
Hi,
You've posted on a wrong community forum.
But here are the links where you should be posting your queries.
1. For ADM1270 post it on Power By Linear.2. For ADR440 post it on Voltage References3. For ADG721 post it on Switches/Multiplexers.Best…
谢谢关注。
通道转换后停顿500ms再次读取ADC效果是一样的.
前端接入信号为100mV .使用ADR440做基准,双极性。
不知道问题出在哪里,很茫然..
Attached are the schematics of our prototype. The analog reference voltage is supplied by an ADR440 at 2.048V and AD5 is grounded on the detector board.
If it appears that my issue is a hardware issue, can you give some guidance on the correct way to…
What are the recommended ADC driver, external reference and reference buffer options?
The AD7961 datasheet recommended ADC drivers are the two single-ended op amps ADA4899-1 and AD4897-1 or differential amplifier ADA4932-1. The low-noise,
Hi Kaos,
We have only two references capable of negative output voltages at this time. These are the AD688 (+/- 10V) and the AD588 (+/- 10V, +/-5V). Neither are capable of a direct -4.096 V output.
A simple circuit for generating a negative reference…
其实用过ADI的IC还是比较多的,没办法一一列出来,就说几个最近在用的,比如基准电压ADR361,ADR360,ADR440,ADR127等等,还有各种放大器,RRIO的精密运放AD8554,低Ib,高带宽,高压摆的电压反馈型ADA4817,超低输入偏置电流的AD549,用来做皮安表非常棒,也是超爱,还有其它一些年代比较久远忘记全名了,也懒得去查。
现在说说我最爱的ADA4817,它的最大特点就是高带宽高压摆并且拥有超低输入偏置电流,带宽上G,压摆印象中是800V/us左右,输入偏置电流是pA级别的…
