Other Parts Discussed in Thread: THS4131 , ADS1271 , THS4521 I am currently using the THS4131 as a driver for the ADS1271 much like figure 70 in the datasheet. However I now want to reduce power consumption and was looking at the THS4521, but the THS4131operates…
Hi Basavaraj,
Lets start by looking at the full scale input range of the ADS8363 (+/- V REF ), in your case +/- 2.5V. The circuit you have around the THS4131 right now will differentially create a 5V signal on the input of the ADS8363 when V S swings…
Hi Chuck
The signal that I am sampling has a carrier frequency anywhere from 200 kHz to 450 kHz. The sample rate is four time the carrier, so from 800 kHz to 1.8 MHz. I am using a board with a ADS1610 Sigma delta converter. The other option that I…
Other Parts Discussed in Thread: TINA-TI I used TINA to build a composite op amp structure, but there are some problems with the DC simulation results, when I use 4.9V and 5.1V differential inputs, the output composite is expected, but when using 5V,…

I have differential Inputs
VS - 2 to 2.7V
VR - 2 to 1.3V
I want to design ADC Card with differential amplifiler.for 14/16 bit ADC…
Other Parts Discussed in Thread: PCM1798 , NE5534 , OPA1611 , THS4130 , THS4131 , OPA1632 Hi there, i'm designing the PCB for a DAC using a PCM179x (either 1798 or 1794a), and have a few questions regarding the layout of components I hope you may be able…
You are correct, but since these groups are always doing devices for the next rounds of test equipment they always have to do better than anything you can buy. In HD work, source cancellation methods are normally used, one of the very few published references…
No kai was right on gain as well - and you are right on frequency - both are related to LG degrading which is what controls HD (partially) -that breaks down as you start approaching slew limiting, in fact I have a rule of thumb about that, but in the…
Other Parts Discussed in Thread: DRV134 , THS4130 , LME49724 Hi,
I am working on a project which requires a single-ended to differential converter driving ~3 meter of shielded twisted pair. The required (differential) gain is Vdiff = Vout(+) - Vout…
Couple of quick things Akash,
1. Where is your DC bias current path for the V+ inputs to the op amps?
2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
