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…
Other Parts Discussed in Thread: THS4503 , THS4222 , THS4631 When I implement a single ended to differential circuit using the THS4503 by itself (no other amplifiers, only passive components/voltage generators/batteries), the simulation results seem to…
Any ways to know if it'd be working with a -2V / 12V supply ?
The simulation works, but it always does (with -2/+13 actually, because the swing of the THS4221 is not that good).
The price is near 2$ for it, but only 1.38$ for the THS4222. The same…
Other Parts Discussed in Thread: THS4222 Hello,
I am looking to design an active filter system for the THS4222. I would like to provide it with a positive and negative supply.
I am looking at different bench-top power supply units. I am considering…
Greetings Vishal,
Two possibilities are:
The THS4222 DAC is capable of supplying up to 100mA.
The OPA2830 is also a candidate. However, the specs in the OPA2830 datasheet show that it will work but it does not cover the entire range of the TALP1000B…
Other Parts Discussed in Thread: THS3001 , THS4222 , OPA832 , DEM-OPA-SO-1A , DEM-OPA-SOT-1A I am looking for an op amp that is intended to be used as a 50ohm doubly-terminated line driver. In the past I have used the THS4222 and THS3001 for this type…
Thomas,
Thanks for the reply. I searched for and found another circuit that appears to do exactly what I want it to. I was able to get it to simulate "well" with the THS4221 op amp. I'm probably going to sample the THS4222 (dual version), and see if…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
