Part Number: THS3217 Other Parts Discussed in Thread: AFE7225 , THS4221 , THS3215 , THS3491 Hi Team,
We are designing a 2 channel DAC circuit using analogue front end AFE7225 part. The output of the DAC we are converting D2S by using THS3217 part and…
Eric,
I think the THS4221 may be a good choice for your requirements. Please let me know if something is missing and I can try to see if there is a better match.

Hi Bernhard,
No. You could use the SN10503 device to build a gain stage with Av = -0.025V/V using noise gain compensation. The statement "Acl, min spec gain (V/V) = 1" only means that the device is compensated internally to be unity gain stable. I have…
I had a look in to datasheet of THS4281. Its not suitable my application.
The THS4221 seems good choice. Before that let me confirm on load resistance, Max drive current and output voltage tolerance.
Meanwihle I will also simulate the performance…
Hi Lucy,
1. If the THS4222 chip operates at a high temperature of 60 degrees, then it could be that the part is oscillating. Have you looked at the THS4222 output to see if there is an oscillating sine wave?
2. It is possible that the large pick…
Hi Simon,
There are quite a few options available in the High-speed TI products list of which some are SN10501 with single channel to SN10503 with three channels, THS4221 upto THS4226 and likewise. They can be found in the products section in TI: http…
Hello,
I could not find any Rail to Rail output op-amp with 2,000 V/us slew rate. The closest would be the THS4304 (790 V/us, 3GHz GBWP) when I search in Selguide.
THS4221 is another possibility (990 V/us) if you can accept an output swing to within…
Nathan;
I agree with the previous posts, breaking up the gain into two stages will allow you to achieve greater bandwidth so that the transient response will be OK for your application. An INA163 is a good choice if you have dual supplies but it is…
