Part Number: PMP9774 Other Parts Discussed in Thread: OPA4377
When we input sinusoidal signal (such as 1KHz signal) on PMP9774 EVM board, we found that the negative half cycle of the signal was not flipped but cut off, so that the part of the cut signal…

Hi,
It depends on the voltage level of the DAC output. Suggest the voltage level should be within 1V, at least 0.1V below the TPS61088's 1.2V reference. So if the DAC range is 0-0.8V, when VDAC=0V, Vo=6.5V, When VDAC=0.8V, Vo=12.4V, then you can choose…
