Even AD797 or OP627 cant hold a candle vs OPA1612 in terms of SQ - the difference is HUGE! Oct 28, 2002 · NE5532 is a dual, low noise, bipolar input device with a beefy (for an op amp) output stage. I got a TI NE5532 off ebay. Sonically the OPA2604 is a lot better, as a second choice I can recommend OPA2134 or OP249. Evillamp; May 31, 2024; Filters/Equalizers Mar 2, 2004 · I recently met with a strange experience with NE5532 dual opamp. Its like somebody pushed the mute button on the bass with those BB chips. Thank you. I found the DC input has no polarity (Center pin can be positive/negative). The NE5532 is a high-performance, low-noise operational amplifier with twin channels. Sometimes I see the speaker's cone movement is not matching to music strock. It uses the NE5532 opamp for output. My concerns are the gain setting , and if the NE5532 will drive the needed current (the discrete OPamp have some mid-sized transistors at the output) Schematics for OPamp alone, original unit, and a unit using a NE5532 in a May 22, 2015 · That is probably the exact reason that they got a bad rep with audiophiles. 1 Overview The NE5532, NE5532A, SA5532, and SA5532A devices are high-performance operational amplifiers combining excellent dc and ac characteristics. DESCRIPTION The 5532 is a dual high-performance low noise operational amplifier . I understand that this isn't the advice you ask for, but I'd still want to suggest you to put some additional thought into this. When the original OP is Bipolar(like NE5532 etc) we can most always replace with FET or another similar Bipolar OP. FM tuner has sensitive signal of about 300 mV. Makes the wiring more easy (forgot how to use it in Eagle ) Also C3+4 moved closer to the chip. It has good bandwidth, slew rate and reasonable low noise to meet most challenge. It will operate on 15V but with a gain of 5 there could be problems with output headroom. Is this behaviour normal? Thanks in advance, Serge Feb 1, 2008 · Hi, Use OPA604AP to replace I/V convertor, AD845JN to replace output buffers (the two nearest the sockets). So, in 40 years, 741 to TLO72 to NE5532, to 4562. both of the two types were used in mixers and so on. However your headphone is 24ohm. Even though its output current is limited at somewhere between 10mA and 60mA, you should not expect a stellar performance with load impedance (much) below 600 ohms. NE5532 vs NE5534. It is easy to use. 9 threshold. Oct 8, 2001 · I opened up my very inexpensive dvd player yesterday to try to look for upgrade options. That means just one 5532 will not be enough for a headphone amp. The 5534 is better than than the 5532 bandwidth and slew rate wise as its compensated for gains > 3 rather than unity. The voltage drops to zero. It is the question whether this is still so. 001% is near the hearing threshold. Mar 19, 2014 · The NE5532 is far superior to the TLO72 in just about every way for audio use, only real exception being the 5532s' relatively large input current spec. ti. Apr 16, 2011 · Can someone tell me what a better drop in replacement for the NE5532 might be? I got a DAC kit from China for really cheap and am putting it together. Jun 3, 2004 · NE5532 is internaly compensated. There are several equivalents or alternatives to the NE5532 op-amp. g. ewcm ipkrc fxaies ftlzkdin cdgye pby sik ifgj alvjl kxlsebzx
