Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hello user6238688,
Welcome to the e2e forums. Our RC4558 and RC4559 are good replacements for those devices.
Which specific voltages did you notice that are different?
Other Parts Discussed in Thread: LM358 , RC4558 , LM321LV Hi Expert.
I have design Amplifying a Piezo Speaker and Volume Control as bellow picture.
But I need lowest cost for this design.
So could you tell me What is Opamp (single power) I can replace LM358…
Kevin,
Your input common mode on pin 3 is 4V which is fine for RC4558. Into a lighter load RC4558 has a better VOH than LM358, especially at low temperature. Typical RC4558 VOH at 25C, is VCC - 0.75V - IOUT * 205 ohms (+2mV/C); this is better than LM358…
Part Number: OPA2132 Other Parts Discussed in Thread: OPA2134 , RC4558 , NE5532 , OPA1678 , OPA1652 , OPA1688 , OPA1642 Hello,
I need to replace the operational opamps in my amplifier due to transistor failure, and --54v went through -17v rails.
DC Servo circuit…
OPA2134 would also be a good choice, but compared to the AN4558 specifications may still be overkill. In this application, you could probably get away with something like a TL072 or other general-purpose op amp. It actually looks like the least expensive…
Hi Alex,
Thank you for reply!
Today, we use TI's 3 different kinds of op amp to simulate, the models are TL971, OPA1641, RC4558. From the simulation results, RC4558 is ideal, but the output is only 3.5V. Is it possible to recommend a op amplifier that…
Bell,
If "OPA" can mean op-amps from other prefixes other than OPA series, then these are high voltage op amps with high VID tolerance (and low cost).
TS321, LM358, LM324 family of devices.
TL031, TL061, TL071, TL081 where 1 = {1,2,4}

Hello Eli,
The LM358 is one of a few that match the requirements you are looking for. To find possible replacements I used the TI Selection Tool under the "Compare" tab and filtered for the following:
Package Group: VSSOP
# of Channels: 2
I have…
Pual,
Every op amp is different so the 'best method' for least chance of problems as seen in blog doesn't always give the lowest ICC.
For low ICC keep the red transistors off. This is output 'railed' high (use no load of course).
