Other Parts Discussed in Thread: DRV135
Hello, I have a commercial audio product that uses INA1650IPWR for input line receiving. I have noticed that approximately 5% of the products have been returned for repair within 1 year of purchase. The problem is usually one channel of the INA1650 not passing audio anymore.
The products are most often used with unbalanced cables, which shorts one side to ground through the Input/Output jack. The relays are used for true-bypass. The device is a set of audio filters, but I have simplified the schematic a bit for this request.
Can you see any design flaws that would cause such a high failure rate?
