DRV603 Questions (Role of some Capacitors)

Hi Paul

I would like to ask you the formula of DRV603 EVM BD circuit and Application circuit of DRV603 Data sheet.

One of my customer is asking Why TI provide different circuits such as EVM BD and Data sheet. Currently The cusomer is using DRV603 for STB and her R/R is 750K/M.

She is planning to adapt the DRV603 for new models after reviewing circuit of DRV603 detaily.

please give me each formula of the circuits and what different things they have between them.

Thanks

Hi, Lawrence,

These values were calculated using a simulation tool like FilterPro or TINA (TI's SPICE program). They are pretty standard op amp filter configurations. It is probably easier to simulate the filter than do hand calculations using formulae.

Hi, Don

Unfortunately I provided the result of Simulation by using TINA and Filter-PRO. Even provide the simulation program to the customer.

The customer does not want to have simulation result but nee to have the formulas. My customer's end customer is the DirecTV located in US and the Direc TV is asking the

formulas to apply the DRV603 for New STBs.

Please understand my customer and I hop you to give me the formula as soon as possible.

Thanks

Hi, Lawrence,

Unfortunately, a few of the guys are out of the office this week. Can you talk to Max about this? He should be able to help you.
