Other Parts Discussed in Thread: THS4131, THS4151
Hi all,
When my customer evaluated THS4141 with the following circuit, the 0.01% settling time becomes longer as follows.
In the data sheet of THS4141, the 0.01% settling time is 304 ns (typ), but it takes a very long time in the evaluation result.
The differential output waveform is obtained when the differential input is changed from -10 V to 0 V. The output level rises steadily to converge to 0V.
Why does the rising waveform slow like this?
Would you give me advice on how to solve it?
Each output from THS4141 is connected by two 75 Ω coaxial cables and is connected directly to an oscilloscope for observation.
The input impedance of the oscilloscope is set to 1 MΩ.
For comparison, when THS4131 is evaluated with the same circuit, converge within 0.2 mV at about 20 μs.
Regards,
Toshi
