Part Number: TL441
This figure is Figure 15 in the manual tl441，There are several adjustable resistors. I'd like to ask what determines the resistance value of these resistors? Are there any typical values recommended?
Part Number: TL441 What are the conditions to make the TL441 work with a single supply, say +5V? Should the ground in the device be shifted? Could TL441-ground and Vcc- be connected together to power-ground? Should the input signal be shifted to make…
Part Number: TL441 Hi Guys,
Good day. We need your help to check the of the TL441 log amp of our customer.
When they adjust the R10 Attenuator it appears to change the gain on both outputs of pins 5 and 11. They assumed that the input on pin 7 would…
Hello Stefano,
Since we have nothing but the TL441 datasheet to reference this is going to be a learning experience for both of us! I will attempt to answer your questions, but some discussion may be needed to get to the answers.
1) what are A2 and…
Part Number: TL441 Other Parts Discussed in Thread: LOG112 , LOG114 , TLC271 Hi there,
I built the same circuit shown on Fig 15 but couldn’t exhibit such a good linearity (except for between 0.01V and 0.5V DC) so i got two questions:
1. Would you…
Hi Alex,
Sorry for the late reply. I need to check with my advisor to allow me to share our schematics. The chip (IC3) with 16 PIN is TL441. The chip (IC1) with 8 PIN is TL592, and the one (IC2) with 14 PIN is AD734.
At the bottom of the board are…
Hello Paul,
Very nice work! Thank you for sharing your TL441 test results with the Precison Amps E2E forum. This will be useful for future reference.

Part Number: TL441-EP Hi,
i need to perform an impedance measurement and i think about using the TL441-EP. I used the configuration suggested in the application information in data-sheet, but what are A2 and B2 and why i need to input the signals both…
