Part Number: TPA3112D1 Hi My question is"Quiescent supply current in shutdown mode."
PowerSupply 12Volt. It will be 1mA at no load. Please review it well. I have attached a circuit diagram. Your data is 200uA.
Thanks...

Part Number: TPA3112D1-Q1 Dear team,
My customer is testing our TPA3112, their load is a 1:2 transformer, pull up /SD to VCC.
Set Gain = 20dB, apply a 1Vpp sine signal to input, TPA3112 cannot active regularly. They see fault pin goes low periodically and…
Part Number: TPA3112D1 Hi team,
My customer is using TPA3112D1 in a special environment: it is designed to drive a load through a isolation transformer. The signal is 500Hz single tone. The problem is occasionally the PA cannot startup. Since the pin…
Part Number: TPA3112D1 I have an issue with this IC. I placed a switch to shutdown the device manually, but the devices goes to DC FAULT each time I activate the shutdown switch AND the supply voltage is over 17V. If I lower to, lets say, 15V and cycle…
Part Number: TPA3112D1 Audio team,
One of our customers using TPA3112D1 is seeing that GVDD is around 5 V to 5.2 V instead of the expected 7 V on multiple separate projects.. AVCC is measured at 21 V. AVCC is supplied from PVCC through a 100 kOhm resistor…
Part Number: TPA3112D1-Q1 Hi
I want following information about this device.
* Is it possible to provide "Output Power vs Supply voltage" at 8 ohm w/ 1% THD and 8 ohm w/ 10% THD ?
If it is difficult to provide it, I want below at least. * Supply…
Part Number: TPA3112D1 Other Parts Discussed in Thread: TPA3138D2 , TPA3136D2 I have recently designed an Audio player using the TPA3112D1. I copied the reference design as close as possible. I am using a 24V power supply. Everything works as correctly…
To everyone that reads this,
The issue in the overheating TPA3112D1 was in not connected Bootstrap capacitors to the BSN and BSP pins to the IC.
Make sure those caps are connected between BSx pins and the switch node, to achieve proper performance on…
Part Number: TPA3112D1 Hello Team,
Posting on behalf of customer. Please note that this circuit, minus the snubbers, has been used on two other products with no issues.
Thanks,
