Hi all! My Topping E50 DAC is damaged. The switch chip that disconnects the op amp outputs from the TRS connector has burned out, so there will be no pop when turned on. and turning off the DAC. The photo shows a damaged chip. Damage to the microcircuit led to a short circuit in the op-amp power supplies (10/5V). I unsoldered this chip, the supply voltage for the operational amplifier appeared and the DAC started working. I shorted the inputs and outputs of the burnt microcircuit with jumpers. Everything works and sounds great. But there is a popping sound after turning off the power to the DAC. I contacted Topping to find out the name of this chip. But Topping, as always, is keeping this information secret. Therefore, I turn to my colleagues on the forum for help in determining the type of this chip.

Hello colleagues.
Thank you very much for the useful information.
Topping responded to my letter and offered a free chip, but for shipping to Ukraine you need to pay $15. I'm still thinking...
