  RE: ADS4129: ADC Input Signal Issue on OFDM Waveform

  Hi, I tried increasing the headroom for OFDM signal by applying +15V/-15V to the both the Amplifiers (THS3091). But it did not create any impact on the signal waveform. The issue was still there. I also tried adding 10dB pad at point B (i.e. TX amplififer...

  RE: THS3091: Sensitivity from Opamps

  Hi Ronald, the output offset voltage will increase with increased gain, because the input offset voltage is also amplified with the gain. One remedy is to use AC coupling by the help of a high pass filter or to use a DC servo, eventually. Can you...

  RE: THS3491: Output noise calculation missing?

  Hey Michael, Yeah that does seem to be the case, this doesn't seem to be included on every datasheet since there isn't a noise section on this on the THS3091/5 datasheet either. Best, Hasan Babiker

  RE: LM7171: 20MHZ X10 times input ,but the Vpp(out) is attenuate 50%

  Hello, Here are two TINA-TI schematics with the initial design you posted and one using a current-feedback amp (THS3091) on the second stage. You can choose a different amplifier based off your requirements, a current feedback amplifier is useful in...

  RE: TINA --ths3091

  THS3091 heated up to 70 degrees Celsius in my circuit. I checked the power consumption of operational amplifier by simulation, and found that the actual and simulation did not match. Actual measurement THS3091 Iout = 16mA, IVs + = 32mA, IVs - = 50mA...

  THS3091: Output attenuation observed above 30MHz

  TI Thinks Resolved

  Part Number: THS3091 Hi, I am trying to amplify a DDS sine wave generator using the THS3901. The DDS can produces a sine wave from 50kHz to 70MHz with an amplitude of 50mVpp. As a test, I set up the THS3901 as a non-inverting amplifier and tested gains...

  RE: Seeking an amplifier suitable for summing multiple inputs in the range of 25KHz to over 1GHz. Gain should not be excessive <5 if possible.

  Hi Arhtur, every OPAmp with current feedback technology should work as a summing amplifier. The advantage of using a current feedback OPAmp is explained here: www.embedded.com/.../4009914 Of course, today TI has some much faster OPAmps compared...
