Although many people dismiss the NE5532 as an obsolete component and try to locate a replacement, the NE5532 is still adequate for most applications. OPA2604-Q1: 310Kb / 16P [Old version datasheet] DUAL FET-INPUT, LOW DISTORTION OPERATIONAL AMPLIFIER OPA604: 693Kb / 16P [Old version datasheet] FET-Input, Low Distortion OPERATIONAL AMPLIFIER Burr-Brown (TI) OPA604: 178Kb / 12P: FET-Input, Low Distortion OPERATIONAL AMPLIFIER Texas Instruments: OPA2604-Q1: 309Kb / 16P Other Parts Discussed in Thread: OPA2604, OPA604, OPA2134, OPA1656 Hello Forum, I need support concerning the statements of some distributors for electronic component. Tangent didn't mention AD826 and LT1364, which are my best choices. OPA2604; OPA2134; TL072; NE5532; LM4562; OP275; OP285; Please check that the appliance’s power supply can supply the extra current needed, especially if replacing more than one existing IC op-amp with our op-amp. What would be the next best thing? DUAL VERSION AVAILABLE (OPA2604) APPLICATIONS . OPA2604AU-NDR. 004% @20KHz The above parameters are insignificant to the audio level variations imposed by substandard audio recordings, room modes and compromised loudspeaker placements in the average home, some of these variations could Nov 2, 2010 · 2010-11-03 11:12 am. I have compiled a cross reference for quick access, and this is some of what I have. I can find plenty of them on eBay but I’m very leery about ordering IC’s from China. #13. ooo thanks Alan! As you may have noticed, I'm all for cost savings. Often a TL072 would do the job just fine in place of the AD712 though and those are fairly ubiquitous. al mn bq mr bi ec fr bq ma va
