Since each TAA2008 has different offset voltage, the output offset voltage will need to be measured for both channel 1 and channel 2 and then resistors will have to be added on the PC board to trim the offset. Below is a lookup table for resistor values for corresponding offset voltages. Both Rx and Ry values should be 1% tolerance resistors. Please refer to the EB-TAA2008 document for more information on this manual trim method using resistors.
