Part Number: DRV612 Dear TI apps team,
I wonder if you could answer a quick question about an application requiring DC isolation between two pieces of equipment (one with audio output, one with audio input).
Both equipments will be connected to the…
Dear Mr. Shibatani,
I checked the mechanism gain waveform of one DRV612 EVM and the glitch confirm the internal circuit start up as said above.

Other Parts Discussed in Thread: DRV612 Hello
In the DRV612 D/S p10, Gain setting is latched during power on.
Would you please let me know more detail
Q1 How is the gain latched in regard to VDD voltage and the time.
For example VDD is more than…
Other Parts Discussed in Thread: DRV612 Although the attached circuit is examining DRV612,
if 10kΩ is attached to RL, a gain of about 1dB will become small from the time of OPEN.
Where should be improved in order to keep a gain from changing? (Is…
Hello Ivan,
Thank you for your prompt response.
"What are your output requirements?"
The product should be connected one of two things. 1) Line receiver such as an amplifier or receiver. or 2) headphones like ear buds or DJ headphones. Is there…
Hello Kenny,
We would not recommend tapping the speaker output and deriving line out from them.
TI has Audio DACs that can do audio processing such as EQ (the PCM5121 or PCM5141 for example) which you could use in parallel with either a line driver…
Hi Shungo,
What is the load you want to drive with TLV320DAC3203?
This device has a headphone amplifier, so it is best suited for 16 or 32 ohm loads. However it could also drive higher gain loads like 600 ohm.
If you want a line level signal, like…
Other Parts Discussed in Thread: DRV612 , DRV632 We have 0.5V RMS audio signal that we need to scale up with 2X gain to feed aux-in of amplifiers. We have 3.3V switching supply and 4.2V linear available on the board. Can anyone help us in selecting the…
