Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi Alok,
Have you got chance to test as suggested initially, disconnect TPA2012D2 analog input and test by AC coupling inputs to GND? So far seems the noise actually comes from the AIC device rather than TPA2012D2?
You need a reconstruction filter to…
Hi Abhineet,
Could you please clarify if the noise is observed at the output of AIC3106 or only at the output of TPA2012D2? This helps to get the proper support.
Best regards, -Ivan Salazar Applications Engineer
Part Number: TPA2012D2 Other Parts Discussed in Thread: AM62A3 Hello Ti, I am using audio codec ( TLV320AIC3106IRGZT) with TPA2012D2RTJR as amplifier, I am getting output of audio codec to INR+- and INL+- but not getting any audio at speaker connected at…
Part Number: TPA2012D2
Hello I am working on an amplifier circuit, but when I power on and enable the amplifier with no input to the left and right channels. my speakers begin buzzing like a beehive. I have connected the oscilloscope to the speaker and…
Part Number: TPA2012D2 Hello,
I have a question about Power on Sequence. of "TPA2012".
In my circuit, 3.3V is applied to "SDR","SCL" pins, while PVDD and AVDD is "Low". Is this harmful to " TPA2012 "?
Best…
Part Number: TPA2012D2 Other Parts Discussed in Thread: TLV320AIC3106 Is the output signal of TLV320AIC3106 comes under the operating frequency range of TPA2012D2.
Part Number: TLV320AIC3104 Other Parts Discussed in Thread: TPA2012D2 Hello, I have developed a cellular device, and I need help to solve the handsfree volume level. The circuit consists of a Quectel EG91 module, a TLV320AIC3104 IC and a TPA2012D2 interconnected…
Part Number: TPA2012D2 Other Parts Discussed in Thread: TPA6120A2 I need to identify a solution to drive the speaker in a push-to-talk remote like the one shown below.
The specs for this remote indicate that the speaker is rated for 0.5W with an impedance…
Part Number: TPA2012D2 Hi Team,
I would like to check with you how should we measure the power level for class D amplifier?
I understand that there is a training video on precision lab to teach measuring class D audio amplifier ( Measuring Class-D Audio…
