Part Number: OPA189 Other Parts Discussed in Thread: TINA-TI , LMC660 Hi all, My customer tried to measure input bias current of OPA189 by below circuit.
In order to predict the offset voltage and Iib, they plotted the values of Rf as 0, 1 k, 10 k, 100…
Hello Peng,
The LPC661 is the low power single version of the LMC660 (quad) and LMC662 (dual). The LMC660/662 (and LPC66x) is our first generation CMOS op-amps. The LMC60xx family is the second generation.
Again, same thing as the 6001/6041...low power…
Hi Britt,
Thank you so much for your help. I also have one more query. I would like to download the Tina Ti component (TSC file) for the operational amplifier LMC660 and voltage regulator MC78L05ACP for a large design project for university. I cannot…
Hi Steven,
Sorry, there is not a replacement for the LMP91200 coming.
When implementing this using discrete amplifiers some suggestions are to use the LMP7721 for the pH Buffer and the LMC660 for the VCM Buffer.

Other Parts Discussed in Thread: LMC660 , TIPD104 , TIPD129 , TIPD135 , DDC112 I am looking to measure the current through a high impedance load (around 1 Giga-Ohm) from a voltage supply of 50 to 200 Volts. I was hoping for a single chip solution but with…
Other Parts Discussed in Thread: LMC660 We have a LMC660AIM that are connected as an ordinary amplifer. Its powered from an 12VDC supply. On the positive input pin we use a 100k serial resistor. The amplifer have a gain of 4 bu feeback resistors from output…
Hello Siyavash,
I recommend using an amplifier with low offset voltage and noise. The LMC660 600 times more offset voltage and greater 1/f noise. In addition, the lower BW of the OPA333 limits the noise whereas the greater BW of the LMC660 will integrate…

Hi,
I need an opamp to amplify the signal from a piezoelectric transducer (piezoelectric disc - 35mm), and I noticed in your document “AN-31 Op Amp Circuit Collection” that…
