Other Parts Discussed in Thread: THS4121 , TINA-TI , THS4551 , THS4541 Hi!
I am using a THS4121 as the CSA of a capacitive sensor that will work as an I-to-V amplifier. When testing the circuit, I saw that the output common mode voltage is 0 V. Supply and…
Other Parts Discussed in Thread: THS4531 , THS4121 Dear TI Support,
I am looking for a fully differential Amplifier to convert bipolar (+/-2.5V) signal from a current sensor (2MHz bandwidth) to differential signal to a 65MHz TI ADC. I found THS4121 and…
Other Parts Discussed in Thread: THS4121 , THS4521 Hi Team,
My customer choose the THS4121 as unit Gain applicaiton, we found that our user guide recommend the value of Rf and Rg is 150 ohm, but right now we changed to 10k ohm for each other, we seem the…
Part Number: DEM-OPA-SOT-1A Other Parts Discussed in Thread: THS4121 Hi team,
My customer would like to use DEM-OPA-SOT-1A EVM boar to evaluate OPA300AIDBVT and OPA657NB/250.
Could you please clarify the package in which feedback resistor and optional capacitor…

When triyng to simulate the Pspice model the folowing message appears:
What causes this? I think that all the parameters…
Hello Suresh,
Could you clarify further? Have you looked at the application section and the circuit layout considerations on the datasheet?

Maxime,
i extract the THS4521 datasheet VOCM spec. it is from 0.8V to 2.5V.
the 1V means TI tested every part at 1V, as Test A conditions shows. So i feel THS4521 is OK as its typical value covers the 0.95V well.
our ADS5294 specs show analog input needs…
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…
Other Parts Discussed in Thread: THS4531 , THS4121 Dear TI Support,
Does Fully Differential Amplifier (THS4121 or THS4531) have input overvoltage protection? If so, what is the max input current to the clamping diodes?
Thanks!
Dan
