Part Number: OPA1654 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Dear Customer Service,
I tried to simulate a simple OPamp circuit with your OPA1654, utilizing your pSpice model from this source http://www.ti.com/product…
Other Parts Discussed in Thread: OPA1654 Hi,
my circuit has a strange behaviour that I can't explain (and get rid of) but I think there is a chance that the source of trouble is the circuit around an OPA1654.
The circuit is a sensor signal amplifier…
Part Number: TL974 Other Parts Discussed in Thread: OPA1654 Hi,
Do you have any Temp vs Ib characteristic graph for TL974, like below,
(OPA1654 figure23)
Thanks
Muk
Fair enough, thank you for the additional information about the desire to further increase dynamic range of the front-end.
OPA1604 is our lowest noise quad, with OPA1664 in 2nd. The OPA1654 is a good quality CMOS offering as well.
There are more choices…
Part Number: PCM3168A Other Parts Discussed in Thread: OPA1654
We are using a PCM3168A CODEC in our design and we are having some issues.
When powering-on (or power cycled), there is a chance that the CODEC will hold SDA low while in reset. We are using…
Hello Tapas,
Adding a coupling capacitor in the signal path before the 4th stage will remove the offset from the previous 3 stages. Then, only the offset of the 4th stage will be present at the output of the signal chain. The coupling capacitor at the…

Thanks for your answer,
I tried your suggestions but the results are the same. I simplified the circuit to a simple follower with one power supply and a sinus input with an offset of 5V:
Instead of the OPA4188 I used an OPA188 to avoid potential effect…
Hi Willie,
I don't see that we have one op amp that meets all of your criteria directly, although the TLE2082 looks like a really good choice and possibly the best fit.
Based on your key functional requirement for the Iccq to be less than 10mA for…
