Part Number: LM324B I am trying to do a low-side current sense circuit. I basically copied a circuit from SBOA190–March 2017. Using the gain formula, I tried for a gain of 20. The problem is, I am seem to be getting a gain of 1. I have double checked…
Part Number: LM324B Other Parts Discussed in Thread: LM339B , LM393B I am troubleshooting this circuit designed by another company.
The LM324B is powered from 3.3V.
The input voltage is to be specified between 9-36V with low source impedance.
The output…
Part Number: LM324B Other Parts Discussed in Thread: LM324 , Hello,
The datasheet indicates that input voltage can be within -0.3V to +40V, without relation to VCC power supply.
Can you please confirm that :
- the device will not damaged by an input voltage…
Are U14 and U15 actually powered? I'd guess they are not, and the new clamping diodes from the input pins to V+ clamp the Lx_MONITOR signals.
The LM324B would have overvoltage-tolerant inputs.
Part Number: LM614-MIL Other Parts Discussed in Thread: TL103W , LM4041D , LM324 , LM4041-N , LM324B , LM324-N , TL103WB Hello,
I need to replace a Texas Instruments operational amplifier that is no longer manufactured LM614. Is there a replacement part?
Regards…
Part Number: LM324-N Other Parts Discussed in Thread: LM324 , LM324B Hi,
Please tell me about the current consumption of the LM324-N. Is the DS description the current consumption per AMP? Or is it the value of the entire Quad package?
LM324 (four AMPs…
But INA597 is over-specification. If I employ LM324B, can I choose a pair of OP to counterbalance the offset?
Like using OP1 and OP4 as a pair or using OP1 and OP2 as a pair.

Hi Ron,
Thank you for your response. Please see the feedback of our customer below.
The datasheet indicates Vcc =5V in LM124 section. I am looking for Io, Ios for condition : Vs = +/-12V ( similar with the section for the LM324B and LM124BA, Vs = (V+…
The -A version has better electrical characteristics (lower offset, lower bias/offset current); compare sections 6.5 and 6.6 of the datasheet.
The LM324-N was acquired from National Semiconductor. TI's LM324/LM324A is the same, but cheaper.
The newer…
