Hello,
I`d like to export LT6230 spice model from LTspice and import this component into TINA to do simulation. But I failed.
Could you please provide a .cir LT6230 model or tell me how to solve this problem?
Or maybe you can recommand another component…
Hi, I am using LT6230-10 for sensing the voltage across a sense resistor with a gain of 10, but when I simulate it does not work when -Ve supply of the opamp is grounded. Below is my circuit. Please suggest.
It's working only when -Ve supply of the opamp…
Hi JL9891,
Unfortunately there is no direct replacement for LT6274 yet. You may want to check the following amplifiers as replacement (depending on use case):
AD8067, AD8033, AD8065, LT6210, LT6236, LT6205, LT6230, LT6233, LT1803.
Hope this helps.
Regards…
Hi
Please provide input (common mode) voltage range and output voltage range min and max for following opamps
LT809 supply +5V, -5V
LT6230-10 supply +5V, -5V
Datasheets' values are so confusing for these two parts. it is not clear from datasheets…
Dear Precision ADC Forum,
I'm designing an electronic load for my lab. The load voltage is sensed with a standard resistor divider, and the load current is sensed across a shunt resistor so that the voltage across it can be sensed in single-ended fashion…
Hi Ted,
To get good performance when using this ADC you really should have a PCB with a ground plane.
Using long unshielded wires for the digital signals between the FPGA board and the ADC board will result in ringing as you see in your oscilloscope traces…
Hi rmurthy720,
The guaranteed DC CMRR of 100dB for ADA4895 is hard to beat for most high frequency devices I searched for. However, I've shown a list of comparable ADI devices you could look through:

Hi All,
I need your urgent help to understand the failure in our PCB.
We had designed the Analog feedback loop to control current through MOSFET as we are using mosfet as virtual load.
when we were using this LOOP with SiE844DF Mosfet, everything was…
