![]() Power supply level for Vcc and Vee are identical at both locations, and the reason is I don't want to do the offset re-adjustment again at the circuit board. However the TL081 which is almost electrically identical to the TL082 does offer offset pins, but only because the 8-pin version drops the second op-amp. ![]() If I paired an op-amp with a trimpot, and then adjust the Vos say to within +/- 10 uV at the breadboard, then move both to the circuit board using ic socket and also the same trimpot is also using socket, assuming the socket contact resistance is equal at the breadboard vs at the board, will I get the same or really close to the Vos that I've adjusted at the breadboard ? The TL082 provides two individual op amps in the same 8-pin dip package, but removes the offset adjustment for lack of pins. terminals for adjustment of offset voltage for applications requiring offset-null capability.The op-amp Vos = 2 mV (max) with the tempco of 20 uV/C, now if I use a 100K trimpot that has +/- 100 ppm/C, what is the final overall tempco for the Vos ?.I can't find what is the range of the offset adjustment using that 100K trimpot in the datasheet ? Did I miss it ? Appreciate if you could point out where is it in the datasheet.Its the jelly bean jfet amp LF 411, datasheet -> Questions about the balance/offset adjustment feature : ![]()
