Need LT equivalent for the M5219 op-amp

[gaetan8888]

Hello

Anybody know a Linear Technology equivalent for the M5219 op-amp ?

It's a op-amp with 625 mw of power dissipation.

I include an image of the specs.

Thank

Bye

Why do you limit yourself to LT?
What is your application?

If the +/-25V supply rails are a real requirement there may not be an acceptable substitute.

closest I know of is Burr Brown OPA2604 which can do +/-24V

Is it a RIAA amp? How much is your supply voltage?

Hello

I want to use Ltspice to simulate few amps circuits and they all have some M5219 op-amp, but there's only Linear Technology opamps numbers in Ltspice.

The M5219 op-amp seem to be same than the 4558 op-amp, but the 4558 op-amp are not in Ltspice.

Thank

LT never made anything that poor

supply V limitation, breakdown V is not usually properly simmed - most op amp macromodels won't care

for a "generic audio" bjt input op amp try LT1007



if you find a Spice op amp model it probably would run in LTspice - can add the .model directly to the schematic, use the universal op amp symbol

If you want to get a visual picture of opamp performance you could check out Samuel Groner's MASSIVE work.

Hello

Here's an amp circuit I want to simulate, since the op-amp drive the output section it need an op-amp with a good power dissipation.

Thank

ulikely that the drive Q are running at more than a few 10 mA, would need <1 mA from op amp to drive their base current, any mismatch in the dual ~5 mA ccs
