Forum Post: AFE5816 Power supply 1.8 and 1.9V
Hi, I would like to ask you a basic question about power supply. Is it possible to use 1P8(1.8V) supply for 1P9(1.9V) and vice versa? That is to say, I would like to use 1.8V for both 1P8 and 1P9....

Hi Koji, The capacitance of the piezo on the EVM is ~25nF. A piezo capacitance of 4uF is a very large load for the DRV2667 . When you increase the capacitance to 4uF the bandwidth will reduce...

Thank you for support. I checked the datasheet again and I noticed that 1.8V(1P8) is for ADC die and 1.9V(1P9) is for VCA die. So I think that we should not use common power supply for 1.8V and 1.9V....

Hi Takumi-san, As you can refer from the AFE5816 datasheet, it is recommended to set the AVDD_3P15 voltage nominally at 3.15V and design the power rail to have variation of less than +/- 150mV. Having...

Hi SF, 1. If you do the math and use figure 13 in the user guide, you may be able to achieve 15Hz. The instantaneous current is 3.3uF*(150/(1/Freq)). The plot at 150V shows an instantaneous current of...
