Hello,
The "GND" circuit here (using OPA1692) is intended to center the JFET input circuit in the middle of the 9V battery. It will effectively force the battery voltage (9V) to track GND to mid-supply (+/- 4.5 V) so the JFET circuitry has headroom…
Part Number: TAS5825M Hi TI,
(1) When using the TAS5825 EVM with PVDD at 20V, BD mode, and 384kHz switching frequency, we observed that the speaker(2w/4 Ω ) output voltage after the LC filter is a sine wave centered around PVDD/2
1.Is the LC filter…
Hi Lydia:
There is already internal 1kOhm resistor for discharge, and our EVM design just has a 0 ohm resistor here between VEE_DIS and VEE.
For example, in my circuit, VEE_DIS is a 750K resistor. Is this a VGL Fail issue?
If so, what is the cause?
…
Thank you for your reply, this is very helpful to me.I did indeed detect ringing on the SCLK, by modifying the connection method, this phenomenon has been reduced. Now the data can be read and written correctly.
Additionally, I would like to clarify why…
Part Number: TPS6594-Q1
We use the single SOC solution (TDA4APE6), and use the PMIC TPS6594133ARWERQ1.
According to the EVM configuration document Powering Jacinto 7 SoC For Isolated Power Groups With TPS6594133A-Q1 + Dual HCPS (Rev. A)
GPIO9 of TPS6594133…
您好
It look like the customer has many questions about this part. My suggestion is to order a BQ25710EVM and follow the EVM user guide, at the same time reviewing the datasheet.
This will be the quick way to get the questions answered.
