I want to build a composite amplifier using the Figure 77 of the datasheet ADA4870-1. It says that the voltage offset is less than 500 uV. I simulate this circuit using LTSpice, when driving ada4637-1 with 0V and monitor the output of ADA4870-1, it is…
ADA4627-1 and ADA4637-1 have NULL pins which are offset adjust pins. If I do not plan to use offset adjust what should I do with the NULL pins? Leave it floating or use 100k Ohm pull-up resistors?
8 * (ADA4637-1 + ADA4870-1)
I am trying to make a project based od ADA4870 figured as unity gain current buffer. Looking on it's 23th page of datasheet i found it connected with composite amplifier and i have some questions now:
1. Is the ADA4637-1 absolutely best amplifier…
I like to get the signal out of the noise and then divide.
You have another problem: The ADA4637 is only stable with a noise gain greater than five.
AD8610 is only specified to operate in a maximum supply voltage of ±13V. Above that, the part will be damaged. If you need ADI part with more than ±13V supply, then you may use ADA4627-1/ADA4637-1 which can go as high as ±18V.
As to the…
Could you check ADA4637? drawback is not so low power, 7mA supply current compared to almost 2mA for LT6275.
G=10 is flat at 1MHz, supply voltage is up to 30V and output voltage is 25Vpp typical.
Slew rate is quite high at 170V/us but not on the range…
