Re: gain reduction of opamp at high frequency
Hi, AD8479 - Input voltage is 10Vpp. IN+ and IN- are given differential inputs.Signal is getting attenuated from 8Khz onwards at a range starting from 10mV.

Hello, I think the 1,6V input voltage describe the differential input voltage of the AD623, correct? What did you set as common mode voltage in your simulations? I think the output of the HCPL7840...

Maybe you are right I didn't consider the common voltage in the simulation. I made a new simulation model this time with Vcom 2.5V. The amplifier works well until Vin 1.3 V differential and then...

Hi Jonathan: Yes, the errors occur randomly. And yes, 0V is from a source. I looked at the buffer amp outputs andthey are clean. Same results when the inputs are grounded. Tom

Hi, Dell,I don't know why transfer limit is 0x1FF8u,may be it is some align. But the size of IDMAC DES1 where this value will be written is 13 bits (12:0 for buffer 1 and 25:13 bits for buffer 2). It...
