PGA281: About PGA281 some questions about your datasheet and simulation results

JIE WANG

Part Number: PGA281

I am planning to use PGA281 to implement the design of small voltage amplification function,i read the datasheet and do simulation find the results is different,Below are the pictures，in datasheet the gain is 1/4,but the result seems 1/2

The simulation is correct, so you can base your design on the SPICE model instead of Figure 38 in the datasheet. We are planning on changing the label on the op amp in the figure to show a gain of 1/2 instead of 1/4. Thanks for catching it for us!
