How is bypass pin voltage looking during power up? Is it getting at VDD/2 or close to it? Is this…
Part Number: TPA0172 Hi,
I'd like to design our product use TPA0172, I bought a DEV KIT from Digikey two weeks ago, when I tested that board and found a problem.
I communicated TPA0172 with an MCU, all other functions are good, I can adjust the volume…
Other Parts Discussed in Thread: TPA0172 I bought a TPA0172 EVM Board, and when I'm working with the volume control, I can modify left/right volumes independently. However, if I mute one channel, the other channel is muted too. Is it the way it works or…
Other Parts Discussed in Thread: TPA0172 Hi,
I'm designing a new VoIP related product. For the audio part, I need an amplifier with I2C for volume control. Is TPA0172 a good choice, or if there are better choices? How long will TI keep this part in…
Hello, I'm trying to adjust the I2C registers on my TPA0172 amplifier, however when I read from the I2C bus, it appears to never complete the power up sequence. Bit 7 of register 5 (mask register) never goes to 0.
I read this information from the…
Hi Zoe,
TPA0212 and TPA0172 are similar devices, although they're not fully pin-to-pin compatible.
