Hi,
I want to upgrade the LPF opamp in my car HU, the stock opamp is NJM-2114 smd, power supply is 8v single supply.
The replacement need to be in smd package and able to use with 8v single supply. I only have LME49720 and OPA2132 in hand right now.
I used to try LM4562 and OPA2132 as DAC I/V and LPF at 15v dual supply and both are okay with me in the different system. I never use any of them with 8v single supply before, so I'm not sure if both will perform well at 8v ?
I'm not so good at solder / de-soldering the smd opamp, so I would like to hear your opinion on this and will decide which one to be start with.
Thanks
