The 5532 is an excellent opamp when used as a simple gain stage but I have reservations when its used as the final stages in CD players where HF hash (which is always present in the signal from the DAC) can I suspect impair the final result. NE5532 Features. Sep 25, 2009 · The LM4562 is faster than the LM833 or the similar NE5532, with a 20 V/uS slew rate instead of 7, and would be a better choice if your preamp's circuit layout includes enough local decoupling capacitance to keep it stable. 1uF cap close to the NE5532. So I changed the standard NE5532 with LM4562 in my Aiyima A07. Local suppliers have a disappointingly low variety of products (my local mail order supplier has a grand total of 3 instrumentation opamps designed more recently than 1990) or operate on RadioShack prices (a dollar for a 2N2222 and the like) and I am in a great position because there is an LM4562 vs NE5532: What are Differences and How to Choose https://www. I never liked the OPA2134. Use a simple resistor, or a J-fet with the IDSS trimmed to 3mA~5mA. As far as I can see, the 4562 has a voltage noise of 2. But when you put them with other Op. designs and one of the boards I ordered (based on TI Tas5613) use two JRC NE5532 opa. #5. impossible ? Thread starter ashok; Start date 2007-03-05 8:45 am; Status This old topic is Jan 3, 2024 · Hi I am thinking of trying opa445's in place of either lm4562's that are in my pre/dac or swapping out some NE5532's that are in my crossover, just to see if and how they may affect the music however, in checking out the specs of each, I am a little unsure that they align well enough not to cause any issues. 1-48khz Supported format: sbc/aac/aptx/aptx-hd Replaceable OP amp chips: SR3609SM, OPA2604, OPA2314, LM4562, JRC5532, OP275GSZ, OPA1612AIDR, etc. The sound is really good with the 2604 providing some Dec 15, 2014 · The lettering isn't perfect for one thing, some appear to be at an angle and some out of line. Originally we intend to upgrade it with opa2353, but apparently it wouldn't work due to this op using single 5v power supply. Easy & Effective. 5V to ±17V. There was only one 0. The LM4562 is available in 8–lead narrow body SOIC, 8–lead Plastic DIP, and 8–lead Metal Can TO-99. Really only matters if you are doing 24 or 32 bit designs for specs only. Jan 7, 2021 · Both is not appreciated. Patreon https://www. Mar 19, 2014 · 2014-03-19 9:23 pm.
