Part Number: TPA2018D1 I just bought the TPA2018D1YZFEVM development kit.
The instruction manual says
Po is 1.7W and Rl Min is 8 ohms
The data sheet for the TPA2018D1 says
3W into 4 ohms. L min is 3.2 ohms
What is the truth? I spent $150.00 on this development…
Part Number: TPA2018D1 My TPA2018D1YZFEVM kit is supposed to auto install a USB driver.
My Windows 10 computer is seeing the I2C hardware but is not asking to install the driver and the driver does not appear to be packaged with the software.
Please advise…

Hello,
I haveTPA2018D1YZF Evaluation Module.
When I downloaded TPA2018D1 Interface i took "I2C Failure" error. Drivers looks okay. I upload last NI VISA Drivers. What should i do with…

Is there a place where to download TPA2028DA, TPA2018D1, TPA6130A2 and TS3A227 I2C drivers ?
Thanks Nicolas
Other Parts Discussed in Thread: TPA2018D1 Hi,
On the TPA2018D1, may the EN pin be used as a MUTE during system startup ? Or, in other words, is there any issue in delaying the low-to-high transition on the EN pin after the power has been applied to the…
Other Parts Discussed in Thread: TPA2018D1 , TPA2028D1 We're currently using TPA2018D1 as audio PA . It seems that you've recently released 'updated' version TPA2028D1. If we have SW interfaces developed and surrounding HW designed for 2018 available, is…
The datasheet doesn't discuss input impedance.
What is the input impedance, and does it change with a change in gain from the AGC?
Thank you,

Hi Kazuto,
Regarding data sheet statement, I agree that one is confusing perhaps it's a typo.
The adjustable range is similar to TPA2018D1, however as I mentioned the requirements to request this kind of change in the process in considerable, I may…
Hi
Most of newer devices are BGA package, although not high pin count if layout is the concern. You may consider TPA2018D1 / TPA2028D1. TPA2016D2 is similar, in QFN package option but it's stereo.
Other options would have both analog and digital inputs…
Hi MJ,
You may take a look at the mic preamplifier portfolio:
Regarding AGC and filtering there are some things to consider: Microphone Preamplifiers | Products | Audio | TI.com
One option is to use CODEC or similar device to perform the required processing…
