Hello Karun, welcome to E2E Forum and thank you for posting your question! If you take a look in the data sheet of the device DRV8662 , you will find this table on the page 5: Here you can see that the op amp inside of the device has a bandwidth limitation, depending on the voltage/gain you are operating with. Theoretically, you could use this device with higher frequencies, but then your voltage gain will go down and, eventually, become unity. Best regards, Marko
