Hi Sir,
My customer is using DRV632 with L/R single end input, may I know how to connect single end input to DRV632?
Should them connect to INR+/INL+ to their signal and connect INR-/INL- to ground?
Many thanks,
Patrick

Hi, Patrick,
The customer may use the second filter topology of figure 8. This is the suggested single-ended configuration for the DRV632:

Please let me know if you have additional questions on this.

Hi Luis,
Got it.
one more question, if customer already connect the IN- to Ground and IN+ to their analog output, what will happen?
Is that ok?
Thanks,
Patrick
Hi, Patrick,
It would depend of the device configuration (if it has feedback resistors or any other component connected to the inputs and outputs). But basically, this device can be used like a standard operational amplifier.
