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…
想使用AD8605 ad8608 进行光电光电二极管前置放大器的设计 它的外围电路该如何设计 比如 Cf Rf 还有输出端滤波等等 有没有相关的参考设计和说明文档 谢谢
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.
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.
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.
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…
Now we use AD8065 from a project. please to help to deal with this issue. Thanks a lot.
In the table as below, when AD8065 output current is 0mA, 3mA, 6mA, 9.1mA and 11.3mA, what value are output voltage Swing at -25℃, 25℃ and 75℃? the schematic…
I have Qustion about AD8605 Offset Voltage Temperature dependence Condition.
The detasheet P4 say
Offset VoltageVOS : −40°C < TA < +125°C MAX 750 μV
The condition is only Vcm=Vs/2 or Vcm 0 to 5V ?
