Hi Martin,
Performed measurements with a couple of PGA855EVMs. On this setup, I used a 2-channel waveform generator (Agilent 33500B) to generate the 3MHz and 3.3MHz fully-differential signal. The PGA855EVM was left un-modified with the input and output…
Hi Corry,
I assumed that you are looking for op amp level shift circuit. Enclosed is two references.

Hello Sujatha,
The recommendations from HSAMPs would be to consider one of the following three devices:
- TLV365 (low cost version of OPA365, no laser trim and volume advantage on 300mm wafer)
- OPA863/A (A-version has improved DC precision)
- OPA607…
Part Number: LMH6551 Hello,
I am trying to design a highly sensitive transimpedance amplifier (TIA) system to amplify very low modulated current levels of a photodiode (order of ~10 nA peak-to-peak). This is my first time simulating/designing an analog…
I looked through the datasheet once again and found PSRR graphs. Do I understand it correctly, that PSRR in our case is a propagation coefficient (frequency dependent) of the noise on the power input to the signal output? And given that it is looks even…
Michael,
There are many different possibilities for this issue. Having more detail on how large the current load is, and the detailed schematic with the two amplifiers would help me to give a more precise answer. Here are a few possibilities.
It is possible…
Hi Ammar,
Since the operating temperature range of -65C to 140C very wide, it is difficult to select a part with radiation harden + high operating range in combined specification.
I think that you may have to go with discrete design approach for the 4-20mA…
Hi Sneha,
I was able to look into our devices and simulated a few with the +/- 3.3V supplies and 500V/V requirement and the biggest problem is the lack of head room. As for a potential device, the THS4561 will be the best device in terms of voltage offset…
Part Number: THS4541 Other Parts Discussed in Thread: ADS8881 , , THS4551 , THS2630 Hi TI expert ,
I am designing a MFB band pass filter for 18bit ADC( ADS8881), the center frequency of BPF is 1kHz, Q = 4, gain = 1, pass bandwidth = 250Hz, stop bandwidth…
