Part Number: THS4120 Other Parts Discussed in Thread: TINA-TI , THS4551 I am running an half bridge to a resistive load.
I am currently supplying 30VDC and 1Amp.
I using the THS4120CDGN to measure the voltage drop across R13 and R12 to determine the current…
Hello Michael:
Thanks again for the list. Very helpful indeed.
I picked up THS4120 from the TINA list. Simulated with your values excepting 1k feedback values, 10mV NA signal, +5/-4.7( neg from TPS604000), lo and behold, output CM is almost 0 (0.1 mV…
Other Parts Discussed in Thread: THS4120 , THS4130 , THS4521 , PCM4204 , OPA2377 Customer looking to THS4120 (or THS4130) for a new design. It will take its input from a hydrophone and output to a AD1974 ADC... I have the THS4120 Datasheet... I was wondering…
Hhm, figure 18 of datasheet of THS4120 seems to be wrong, as the front page says that the THS4120 is fabricated in CMOS?
Vahid, what frequency range are you interested in?
By the way, you have seen that the THS4120 provides 1fA / SQRT(Hz), haven't you…
Hi Matthew,
1. What kind of sensor are you using?
2. Is it current or voltage output?
3. Does the sensor have a single-ended or differential output?
The THS4531 is a good choice of a fully differential amplifier, however if you want high input impedance…
Dear Samir,
Thank you very much for the information. I'll read the documents carefully, because I have, indeed, doubts with FDAs. Can I email you with the details?
About TINA-TI, my mistake. I thought that the wires would connect themselves as soon…
Other Parts Discussed in Thread: THS4503 , THS4131 , THS4120 , ADS1675 , THS4121 Hello! I want to use ADS1675 for measurement 25 usec pulses with amplitude 2,5V and 2,5V offset. Pulse repetition frequency is 8kHz. I want to use fully differential Bessel filter…
Hi Anil,
Thank you for the explanation.
Unfortunately there is no setting to make the ADC treat an input signal of 0V as +/-0.625V. The only way I can think of is to use a fully differential amplifier with the -ve input tied to 1.25V and the +ve input…

I wanted to design active band-pass filter in FilterPro with:
center frequency = 50 kHz
bandwidth = 100 Hz
