Hello again Paulo,
In case you could not locate the LME49860 TINA-TI model off the web (it does not show up there), I've attached it below. You can get it if you open TINA-TI and search for it under "Find Component" (icon showing finger pointing to…
LM4562 is the same chip as LME49720 (LM4562 is old name for this chip), and seems also as LME49860. Only one difference for LME49860 - higher limit for the supply voltage (maybe selected in manufacturing process). LME49740 is also the same, but four channels…
Hi Chen Jiao,
The best replacement for the LHV870 seems to be the LME49860 and it comes in a 8 pin SOIC package. Is that pin-to-pin for the package you are currently using?
As far as replacing the LM6588, I would look at these:
LMV881
OPA551,…
What is the status of the LME49860? If the 36V LME49720 is EOL and the 44V LME49860 is not, then this isn't really a problem.
What is the status of the LM4562? If the LM4562 is not EOL then the LME49720 really isn't either: They are the same part.…
Vladimir,
I also downloaded the OPA1602.lib file linked in this thread, and tried it with the best free SPICE simulator available (LTSpice IV ). I had some initial convergence failures because the model's pinout didn't match the generic op-amp in LTSpice…
Other Parts Discussed in Thread: OPA2604 , LME49860 Hi,
I have a personal project to build an audio equalizer base on state variable filter, I have check in TI Tina and using LME49860 opamp (the other candidate is OPA2604), everything looks fine but…
Thank you for the link Victor.
"[OPA1612] has no data for to drive 600 ohm load."
The 600 Ohm THD load data is featured on page 1 of the datasheet and also characterized on page 8.
The OPA1612 does have a higher maximum Ib. The advantage of the…
Hi Thomas,
The distortion is much lower, though noise appears better on the old though the readings are different. The OPA1612 and OPA1642, distortion is much better. Replacing the lesser quality opamps in another Technics player with the OPA1642, the…
Other Parts Discussed in Thread: OPA1641 , OPA827 , LME49860 , THS4601 Hi,
I have seen in one post about minimum GBW for a filter, right now I have an audio filter project base on state variable filter using LME49860 & OPA1641 or OPA827 with:
F: 665Hz…
