Hello Yatao, What is the frequency range of V2? In terms of the OPA172, the bandwidth of the amplifier for the second stage may be the cause of not being able to generate the output range of -5V to 5V. With a gain of 10V/V, the output should stay within…
Hi Yatao,
1. The stability analysis for CFAs is different. The stability is determined by the value of the feedback resistance, as described in the CFA videos.
2. The simulation models are not perfect, and you should defer to the datasheet for capacitive…
Other Parts Discussed in Thread: THS3061 , THS3062 , TINA-TI In the enclosed buffer I have a slight ringing at 20 kHz with a 2V square wave input. What's really crazy is that when I build the same circuit with THS3062 and AD8620 it oscillates wildly.…
Hi Ronald,
I think THS3062 (current feedback amplifier, 300MHz unity gain bandwidth, 7,000 V/us, +/-15V capable, dual), or THS3122 are good possible candidates to try in place of the LM6172 (although I'm only going by the datasheet specs and I've not…
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…
