Other Parts Discussed in Thread: TPS7A39 , TPS7A49 , LME49600 , OPA1622 , LM317 , TINA-TI , LM337 , OPA1612 Hello dear Ti community. I'm using your LDO's for more than few years. My first choices are TPS7A4701/3301 and TPS7A49/30 and TPS7A39 (dual reg in…
Other Parts Discussed in Thread: OPA1612 , LME49600 , OPA1622 , BUF634 Hello dear Ti community. I just want to ask, how to build a proper sallen-key filter (2 stages or more) to avoid high common mode distortion? It's rather hard task to minimize resistor values…
Hello Mohamed,
I reviewed the datasheets for the LME49600TS/NOPB and BUF634FKTTT. They are pin-for-pin, functionally compatible and use the same DDPAK/TO-263 package. Both have -Vs connected to the power tab. Electrically, they are very similar amplifiers…
Other Parts Discussed in Thread: LME49600 I'm currently working with LME49600 and it calls for a mechanical drawing of "KTT0005B," and has a specific land pattern. This package is very similar to the KTT package with a few minor size differences.…
Hi Alex. So there is nothing to be done in terms of performance? Or overall design? How about moving U1B after U1D stage just to be able to put OPA1622 in his feedback loop? Does it make any real diffrence? Most buffers (standalone like LME49600 or typical…
Other Parts Discussed in Thread: LME49600 , LME49990 , PCM1794 , SRC4392 Hi,
I'm developing a headphone DAC+AMP. I'm going to use TI's products for all stages. So far I have decided to use
PCM1794,LME49990,LME49600 and TPS7a4700 for regulation…
Hi Keith,
I haven't tried it, but you should theoretically be able to drive the LME49600 directly from the PGA2320 without an extra op amp. However, using an op amp with the LME49600 will correct for offset and ensure stability. If you find that there…
Hi Tammam,
You should just be able to use the LME49600 as a buffer as indicated in the diagram below:
Or, you can use the LME49710 with the LME49600 as a current driver/buffer for the LME49710 in its feedback loop, as shown below:
Is this circuit above…
Hi Marc,
Randy is right, audio op amps would make a great choice. Might I suggest you take a look at the LME49990.
The voltage noise density graph is on the front page of the datasheet and the other specs seem to fit your needs. (0.88nV/rtHz @ 1kHz &…
