Part Number: LMC6484 It appears from testing our design that the output resistance of the LMC6484 opamp varies when the opamp reaches saturation.
In our application we have configured the opamp as a follower and have 270 ohm seried resistor connected…
Part Number: LMC6484 It seems to be implicit in note 12 that input voltage range can be exceeded -
" Note 12: Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings "
Is that correct?
What…

We haven't heard back from you so we assume this answered your question. If you need additional help just post another reply below.
Thanks

Hi Samuel,
Then most likely what was happening is that you were injecting environmental noise (line noise, switcher noise, etc) into the high impedance (300k) point. The inputs to DMM's are very noisy, and the DMM leads were acting like antennas -…
Part Number: LMC6484 The datasheet states an input voltage range of (V-) - 0.3 to (V+) + 0.3.
The datasheet also states a maximum current at input pin of +/- 5mA and note3 refers "Limiting input pin current is only necessary for input voltages that…
Hello Kum Hoo,
I checked the UL Online Certifications Directory for the LMC6484. The directory did not list it, or any other operational amplifiers. There may be UL certified products that contain the LMC6484, but we have no information about such products…
Hi, forgive me if this is a stupid question but I am not good with circuits. I am using the LMC6484AIMX op-amp as the basis of a transimpedance amplifier. I have included a picture of my circuit. It simulates correctly with the parameters shown, and I…

Part Number: LMC6482 Other Parts Discussed in Thread: LMC6484 , , OPA4196 , OPA2196 Hello,
Does TI offer a similar spec'd part to the LMC6482 LMC6484 but in smaller package size?
Thanks, Adam
Hi Eddie,
1.) The OPA171 is also a CMOS amplifier. The two main differences between the LMC6484 and OPA171 are the input bias current (20fA vs 8pA typical) and the power supply voltage (15V vs 36V). There are of course many other differences such as…
